CorkSport Banjo Bolt 1986-1995 RX-7 & 2004-2011 RX-8
The basis behind this part is rather simple. A rotary engine relies on the external oil coolers to keep engine temperatures down. The CorkSport Banjo Bolt is made with an 1/8″ NPT fitting on the end to enable you to install a sensor for either an oil pressure or oil temperature gauge. The idea for this part originated from a customer who didn’t like the look for function of current oil filter adapter plates. Many aftermarket oil gauge adapter plates cause interference with intercooler piping and are an unattractive mess.
We start with a solid steel 23mm hex bar stock. The ends are turned, tapped, and threaded using a CNC lathe, and the middle is finished with offset oil passages to improve oil flow. Finally, the banjo bolt is run through a deburring process, cleaned in an acid bath, and yellow zinc coated for years of hassle-free use. From us, the end is fitted with an 1/8″ NPT fitting (with plug in case you ever need to remove the gauge sender, or are waiting to buy one) that utilizes a straight-through design to ensure accurate oil readings. The banjo bolt also comes with two (2) copper crush washers to ensure a leakproof seal.
The CorkSport Banjo Bolt was designed specifically for the Mazda Rotary engine. We have tested this part to work perfectly with the OEM oil cooler lines as well as our CorkSport brand Stainless Steel Braided Oil Cooler Lines. The bolt installs in minutes with simple hand tools (23mm wrench, socket, & torque wrench) in minutes.
The CorkSport Banjo Bolt is available today at a price that pales in comparison to the level of quality and time invested in the design and precision manufacturing of the product. As with all our CorkSport brand products the Banjo Bolt ships with all the hardware you need for installation, and also includes full color instructions and telephone technical support.
CorkSport Power Series Air Box for the 2010+ Mazda 3 with the CorkSport SRI
After the release of our popular Mazdaspeed 3 Air Box, there has been an increased demand for a 2010+ Mazda 3 Cold Air Box. As a result, Corksport is proud to announce the release of our thermally isolating air box for use with the CorkSport Short Ram Intake. The air box mounts to factory locations and limits the ingress of hot underhood air into the intake system of your Mazda 3.
The CorkSport Power Series Air Box is made from high temperature resistant fiber reinforced plastic (FRP)
that has a full gelcoat on the outside as well as an automotive grade finish on the inside. It is ready for paint
to compliment your engine compartment and styling of your vehicle (or may be left unfinished). The air box features a fully sealed lid with 4 socket head cap screws attaching the lid to the box. The box features a small slit for the MAF sensor wiring to keep it hidden from view. It also includes a mounting hole with bolt to keep your vacuum line up and out of the way for a nice, clean look.
Our 2010+ Mazda 3 air box has gone through several design iterations to ensure that it will be an effective and cost efficient way to help decrease intake temperatures and also give your engine bay a stock look. We have observed that our CAB design will decrease temps roughly 30 degrees during highway driving and up to 60 degrees in stop-and-go traffic (decreases heat soak).
Power Series Exhaust for the 2011+ Mazda 2
This system was specifically designed for the North American version of the 2 (or Demio). The exhaust will improve vehicle throttle response as well as give your 2 a slightly louder, and deeper tone.
The exhaust installs in about an hour and includes all the necessary hardware to complete the installation. It fits with all existing and future CorkSport brand parts and offers a design and sound that will set your 2 apart from the crowd.
Our CorkSport Power Series Exhaust is made from 58mm diameter fully TIG welded T304 Stainless Steel, that gives a quality and look that will outlast coated or plated mild steel systems. The kit includes a midpipe with resonator and a muffler which features a 90mm double wall tip. The system also includes a racepipe (cat delete, which is for off-road use only), which can be installed or left off the vehicle. The midpipe slip fit design utilizes a two bolt clamp that allows you to switch between the racepipe and factory catalyst pipe (does require one cut in the factory midpipe).
Being the first purchased Mazda 2 in the US, our 2 has been through several design changes and versions of our prototype exhaust. The final product is a result of many months of testing, which delivers a non-overbearing low tone. The 58mm exhaust has been paired with one small resonator up front and a larger muffler in the rear to give it it’s unique sound.
CorkSport Front Swaybar for the 2010-2011+ MazdaSpeed3
Due to the popularity of our adjustable rear sway bar, CorkSport is proud to announce the release of our Front Sway Bar for the 2010-2011+ MazdaSpeed 3. This part was specifically designed and tested for the Mazdaspeed 3. The Corksport front sway bar improves handling by stiffening the link between the front wheels. This allows the vehicle to maintain ride height and comfort, while minimizing body roll during cornering.
To start with, we engineered our bar using a 3 peice design, which allows for greater torsional strength, and smoother travel over one peice designs. The 3 peice design also allows a hollow 1 & 1/8” bar design, which helps maximize stiffness, while minimizing weight. The bar ships fully powdercoated to protect it from the elements, enabling it to maintain it’s torsional rigidity. It also includes Energy Suspension brand polyurethane bushings and zinc plated brackets with grease fittings so there is no need to remove the bar for re-greasing like the stock bar.
The bar was designed with the CorkSport rear sway bar in mind. The front sway bar is not position adjustable by design. The increased bar diameter has been engineered to match the middle setting on our rear sway bar. If you prefer more under or over-steer, simply set the rear bar firmer or softer to match your driving style. The front sway bar is 45% stiffer than stock and does not require you to modify your end-links.
