How to Series: Service and Lubricate Your CS Dual VTA BPV

Hey guys! Brett from CorkSport here today, and I’m ready to show you a basic guide to follow on how to service and lubricate your Dual VTA (or any BOV for the most part.) Typically it’s good to do this every couple oil changes or so.

The main things that you will want to inspect is the O-Rings, and look for any contamination. Clean off old grease, dust, or grime.

Don't forget to inspect the O-Rings.

Fully Clean out the inside of the valve housing as well. Make sure you evenly coat it throughout the housing. Also be sure to lubricate the piston and the O-Rings as shown. We Recommend Lubriplate 105 as your go to grease for this valve!

Make sure you evenly coat it throughout the housing.

Reassemble the valve and reinstall. Be sure that you didn’t drop your gasket on the bottom when you serviced it!

If you would like another visual aid, you can also check out this video here: How to Service your Blow off Valve/ Bypass Valve. In this video, the CS preferred grease was not used. However, it will help you to understand what needs to be done.

Reassemble the valve and reinstall.

Shifty Things Getting Shifted

CorkSport has that perfect solution for upgrading the shift knob while maintaining an OEM look.

How is our CorkSport family doing this summer? Good I hope! The CorkSporteer’s are doing very well over here in Vancouver, Washington, constantly on that grind to bring more parts to the market. We always have our customers’ best interest in mind, and will do whatever we can to help our CorkSport family reach their goals. With that being said, I wanted to make sure to remind everyone of a part that is considered to be the most intimate part other than our CorkSport Steering Wheels.

We all know that the stock shift knob in our Mazda’s can get worn down and look like it’s been through some abuse, especially with how hard we bang gears! CorkSport has that perfect solution for upgrading the shift knob while maintaining an OEM look. Using real leather, red stitching, and adding a CorkSport logo, this shift knob is a must for anyone looking to upgrade.  Here are a few extra tid bits about the knob:

  • Made from high-quality leather
  • Weighs 320 grams
  • Hand wrapped and stitched
  • Perfect design to comfortably sit in your hand
  • Hot/cold temperatures do not affect this knob as much as OEM or aluminum knobs

The CorkSport Leather Shift Knob comes in at a total of $89.99, and includes a limited 2-year warranty against manufacture defects.

The CorkSport Leather Shift Knob comes in at a total of $89.99, and includes a limited 2-year warranty against manufacture defects. The thread pitch of the knob is the same as almost all Mazda’s so whether you have a regular Mazda 3, or a Mazdaspeed 3, this knob will fit both of those applications.  Here is the link for that:

CorkSport’s New Mazdaspeed Front Lip

This Mazdaspeed with CorkSport's new front lip has style and speed.
Check out this stylish Mazdaspeed.

Hello, CorkSport family! If you haven’t visited our New Products page lately, then you’ve been missing out on some cool product releases. Look at this picture. Can you guess which part I’m referring to?

I’ll give you a hint. It starts with the letter L, and ends with an I and a P. That’s right — the lip!

Why we created a new Mazdaspeed front lip

At CorkSport, we’re committed to supporting the Mazda community and always strive to bring new, cool mods to the table. Mazda decided they’re no longer going to support the Mazdaspeed platform, but as a leader in the Mazda Performance market, we’re doing our part to keep the platform alive. Due to that commitment, we believe it’s up to us to push the platform and make sure we’re the leading competitor in this market. To achieve this, we did some research and found what the market was missing.

Our research and commitment manifested in the creation of a part that increases your Mazdaspeed’s style: our new front lip. In our research, we learned that people have been trying to mold STI lips onto the front of their Mazdaspeed3s, and we knew the direct fitment style CorkSport is known for would not only give us a HUGE edge over eBay components but would allow us to create an incredible part.

The new CorkSport front lip

With a new CorkSport Mazdaspeed front lip, you know your ride is going to look stylish.
Take a look at that sick CorkSport Mazdaspeed Front Lip.

In developing this front lip, our engineer Barrett spent countless hours making sure this part would be a direct fitment for ease of installation and would deliver a clean, sleek look. Molded from 3mm ABS plastic with a black coating, our new front lip is a no-brainer when it comes to adding extra style to your Mazdaspeed. As always, we tested this lip to make sure that it would withstand high winds (around 140mph, to be exact) for all of our “Mexico” racers. Passing this test gave us the confidence we needed to be sure that we could offer a product that not only looked good but could withstand daily driving abuse.

Thinking about purchasing this front lip? Here’s what you need to know:

  1. $224.99 is the current list price — that’s 10 percent off the original price of $249.99!
  2. Two-year warranty from manufacturer defect.
  3. One-hour install time.
  4. With the purchase of the front lip, you get a free CorkSport trucker hat — only available through the purchase of this front lip!

Please note: This lip will not work with the CorkSport aluminum skid tray. The mounting locations do not line up.

Lastly, don’t forget, when you make a purchase with CorkSport you become part of our family. When you invest in us, we invest in you.

Recovering a Relic of the Past: Ryan’s Mazda Story

Sometimes your old car is just waiting to become your new car again. See how Ryan’s old RX-7 reentered his life.

My name’s Ryan. I’m a Mazda guy through and through. Currently, I’ve got a 2016 MX-5 Club as my daily driver with a ‘95 Miata converted to an Exocet as my most recent project. As the Exocet becomes more stable and less of a project, I started thinking about what I should work on next.

The ND is my 14th Mazda vehicle in as many years, so this new project was definitely in my wheelhouse — I wasn’t planning on straying far from my roots. However, I didn’t realize at the time just how close to those roots my next project’s journey would take me.

The story I have to tell doesn’t involve the ND, or any of the dozen cars before it. Like any great story worth telling, you have to start at the beginning. …

Sixteen years ago, I got my first car. It was a 1988 Mazda RX-7 10th Anniversary Turbo II. Not before, or since, have I loved a car so much. Not for lack of trying, of course — those of you that know me well can attest to my sample size. But you never love a car as much as your first. Some of my most vivid memories of young adulthood were made possible by this car. I can still hear the engine winding out, carving through the forest roads outside of town back when I was so sure I was invincible, and that the tires would always hold.

I can still smell the summer air and remember fondly the adventures that car took me on. A friend and I went on an adventure in that car that took us to the heart of Texas and back in a handful of days. It was a car full of memories. Then, when I was a younger man in a moment of weakness, I sold my RX-7 because I was in school and needed the money. And that, as they say, was the end of that.

Twelve years later, I was talking after dinner with a friend I hadn’t seen in years. We started chatting and got on about cars and the good ol’ days, and I started wondering about my old car. That night when I got home, I remembered I still had a folder full of old paperwork for my old RX-7 stashed in a closet. Looking through documents that my younger self couldn’t care less about, I found a treasure trove of receipts, service records, original brochures, and flyers — even before I got it, someone had clearly loved this car. I made a decision right there: I needed this car back.

Over the next few weeks, I tried to figure out how I was going to find the RX-7. And also, if I did find it, how was I going to afford to get it back? Late one night, I logged onto the RX7Club forum for the first time in over a decade and looked in my inbox. Empty. Then, just in case they kept old messages, I looked in my sent folder and found a single message — a message I had sent to the new owner of my RX-7 almost 12 years earlier. He hadn’t logged into his account since 2010, but I shot a message out into the void and waited. A few days went by, and then in the middle of the night I got an email.

Turns out, amazingly, he still had my old car.

The catch? After he bought the car from me, his wife had some medical issues that prevented him from doing anything with it. So my old RX-7 sat. And it sat. There in a field just outside Yakima, Washington. For 12 years, it sat there; with the windows down.

The ravages of time have not been kind, but thankfully the damage isn’t irreversible. As a bonus, he never even changed over the paperwork and I’ve technically owned the car this entire time.

Sometimes your old car is just waiting to become your new car again. See how Ryan’s old RX-7 reentered his life.

So, of course, I did what any rational adult who catches the nostalgic scent of his youthful misadventures would do: I asked him if he would consider selling the car back to me as is. He told me he felt bad about letting it sit, and that because the car meant something to me, it was mine if I wanted to come get it. I shot a quick text message to my Dad to borrow a truck, another to (frequent blogger, race car driver, and all around good guy) Derrick for a trailer, and a third to my friend Trevyn to enlist a copilot/co-conspirator, and the plan was set.

We headed out early on Saturday and drove through snowy mountain passes, over rivers, down sketchy dirt roads, and eventually arrived at what could charitably be described as a graveyard for sports cars. We found the RX-7, loaded it up, picked through my RX-7’s one-time-owner’s warehouse of spares for a few odds and ends, and headed back home. Now, my first Mazda is sitting safely in my garage, out of the weather.

Sometimes your old car is just waiting to become your new car again. See how Ryan’s old RX-7 reentered his life.

This car is largely responsible for the person I am today. It ignited my passion for cars and all things mechanical. If you’re a rotorhead in the Pacific Northwest who has a line on some black interior parts you could part with, let me know — this interior is trashed. If you’d like to keep up with the car, you can find me (@mrryanbaker) on Instagram. I made a post on there about the RX-7 that was a little more succinct. I try and post about the cars as much as I can, but forgive me if I end up distracted by projects.

Finally, like I said in my Instagram post, “Welcome home Annie, this time I’ll do it right.”
