STILLEN is happy to offer our pre-existing Z tube customers with these silicone couplers that eliminate the common failure point of the Infiniti bellows couplers. The factory Infiniti bellows couplers are prone to premature failure due to the fatigue caused by the constant rocking of the engine. Previously, the STILLEN Z tube kit required re-using the factory bellows style couplers. Now, with the STILLEN high performance silicone couplers you can rest assured you will not experience the dreaded Infiniti P0171 check engine light due to your torn Infiniti G35, FX35 intake couplers.
