I don't care what anyone says this is a great product. Looks great and is sturdy as a rock. It is true that the coupler for the turbo inlet pipe side doesn't fit but that is not an issue. I had to trim an inch or so but they made it long enough to fit a FMIC. It is hard to push on but what hose isn't. Just spend the extra 15 minutes to work the hose onto the turbo inlet pipe with no lubrication, corksport tip of course. I'm running over 20 pounds of boost and it hasn't moved one bit. I literally couldn't ask for a better part.

I just installed this along with the BPV on my 2008.5 Speed 3; straightforward installation, but the experience made me really want to have a CS SRI instead of the stock breadbox of an intake! Oh yes, it will be mine...

This is a superb item it looks so much better than the factory hose and it married up to my Turbosmart Kompact bov perfectly!
Love the extra length and tight fit, no cutting to fit just a bit of spit to lube it up!
Thanks very much guys!

I bought this as an upgrade to my current one since I bought the bypass valve as well. To make things short, this is sitting in my garage as a 40 dollar paperweight.
First the product looks and feels good compared to the stock hose. But i had to trim mine to even fit into my corksport Sri and inlet pipe. Secondly the hose itself is nearly impossible to insert into the inlet pipe. The use of a lubricant was needed to insert it.
The biggest thing that annoyed me and literally made me waste more than 4 hrs on this hose was the fact that it was impossible to tighten onto the inlet pipe. Everytime I get close to tight the tube itself would somehow slide off the inlet pipe, it was not staying in place. I eve removed my battery box to get more room and leverage and the tube and clamp would still separate. I also tried using the stock clamps but the corksport tube is too thick for the stock clamps....
Not very satisfied with this product.. Everything else has been great but this leaves a sour taste in my mouth

Only issue I had was it is a little small for on & kind of a pain :-(, if it was just a bit larger diameter ( people are saying it should be about 1 1/4 i.d. ) it better :-)
Had to trim some length also but no biggie

I didn't have any of the issues listed in other reviews about being to long or hard to install. Top tip for easy install use dish soap to lubricate , NOT soapy water just plain dish soap, goes on super smooth took about 10 min.

Product is of high quality material, definitely better than the stock rubber hose. Only problem I had was it was 2 inches longer than it should have been. I don't know if that the case with a aftermarket TIP but I'm using a forge v2 bpv and stock Tip with SURE sidewinder intake. Had to cut it down to fit but after that it fit nicely and the clamps corksport sent seem like it'll hold better as well. Nothing short of a great product I'm sure it's meant to be a perfect fit for all corksport mods though :P

Very happy with this product! My stock hose was kinking because of its length and my Forge v1 BPV angle. This hose solved my problem perfectly and added a little more style under the hood. I had to do some trimming, about 2in or so to fit on the CS Stage II SRI+TIP. I have an '06 MS6. Did not have any problems fitting this onto the TIP or my BPV, just used a little silicone spray and it went right on.

Harder to install than I thought. I have the TIP and Injen CAI. Removing the battery box gave me enough clearance to pull the old one off and put the new on on. The Injen CAI has a coupler in the way so I had to position the bolt from the new clamp between the two wiring harness conduits. Hope it doesn't rub too hard. Also had to adjust the angle on my Forge BOV so the tube would fit and the BOV wouldn't rub on the inter cooler shroud.

Installed these item onto a Corksport SRI was a very tight fit and had to cut about 2" off the house but that was also going onto a Forge BPV. Still awesome product
Randy Scrivner09/18/2013, 02:15 AM
This thing was super tight to get on the cork sport turbo in let pipe. I had to take a pocket knife and clean out the inside of the hose to make it anywere close to fitting. It took me forever get it to work. Super aggravating even useing motor oil as lubricant it would not work. It was also too long. Oh and good luck using one of those fancey clamps on the end of the tip. This is absolutely the worst most aggravating piece I've put on my car yet. But saying this corksport is still awesome. But this hose sucks.

I purchased this to replace the old stock one. It mounts up nice to my HKS SSQV but there is some clearence issues with the plastic intercooler shroud. other the that it is a well built piece of tubing that I would recommend to anyone with a Speed 3
Nicholas Cannon06/11/2013, 09:02 AM
Awesome looking hose! Install was easy but getting the hose to slide into place on the TIP end was a PAIN IN THE A**. I probably could have put more silicone spray on it but i was halfway into it so i twisted and twisted the hose to get it in far enough to clamp. Not sure if that is the wrong way to do it but its on there good. Getting it on the BOV end was cake. All in all Great product! :)))
Andrew Cordero06/03/2013, 04:17 PM
Purchased this with the SRI II - Pipe fits VERY tight on the TIP. I actually had to lube it up a little just to get it on far enough to clamp it. With the 2013 MS3 I noticed the tube actually fits better backwards. Due to the tight fit had to cut about 1 in of hose but perfect afterwards and looks great!
Make sure to check the clamps for surrounding hoses mainly coolant system hoses to make sure the clamps are rubbing if need be you can move the screw/Spring clamps to allow for a better fit.
Additional Notes for those using the stock Mazda TIP
With the Stock TIP the hose fit perfectly - Just in case anyone is looking at using this pipe with the stock Turbo Inlet Pipe (Plastic one).

very good product
Sungkook Choi02/04/2013, 05:48 PM
Fits perfectly and the install is pretty easy.
I would recommend getting this at the same time as the SRI as it would save a little time on the install.
If you buy the Boost Tubes with this you also get a discount!
