The CorkSport Performance Boost Tube Upgrade is made to get the most out of your 2.5T Mazda at an affordable price. The OEM tube expands 12% at 20psi (peak pressure we have seen at intercooler outlet) when cold, and even more when heated up by the engine due to the use of flexible rubber with 1 layer of reinforcement. This expansion robs your car of consistent boost levels and hurts throttle response. The CS boost tube expands 3x less than OEM when cold and will stay consistently strong at higher temps and elevated boost levels due to its high temp silicone and 5-layers of reinforcement. Plus, the larger than OEM diameter provides a large volume of boosted air right before the throttle body, a method proven to improve throttle response on our GEN2 Mazdaspeed3 FMIC kits.
The OEM boost tube is made from very similar if not the same material as the OEM Mazdaspeed boost tubes which were prone to cracking & failure as they age. It’s easy to see the 2.5T having much of the same problem down the road, causing boost leaks and a poorly running car. The CorkSport boost tube eliminates this issue as silicone is longer lasting, stronger, and more resistant to the elements than regular rubber. Plus, if this is the first mod in a build, the CS tube is ready for elevated boost levels that could cause the OEM tube to fail prematurely.
Each CorkSport Performance Boost Tube comes with upgraded T-bolt clamps. They offer more secure clamping than the OEM worm gear style clamps and a wider clamping area to ensure a good seal. Plus, they are made from polished stainless steel for a great look and high corrosion resistance.
