Our Bigmouth™ replaces the flexible, ribbed factory rubber intake tube and plastic turbo inlet pipe. The OEM pieces create unwanted turbulence and are susceptible to cracking. The Bigmouth™ effectively increases air flow rate, consistent boost pressure, and a more responsive throttle for your Mazdaspeed driving experience.

Silicone
The Bigmouth™ is constructed with high performance silicone that is reinforced with 4 layers of nylon and a core wrapped in steel wire. The silicone protects the cooler intake air from high engine bay temperatures. The steel wire that wraps throughout the silicone body of the Bigmouth™ acts as a rib cage. The Bigmouth™ rib cage promotes rigidity and prevents the silicone from collapsing. The rib cage design is very important to performance of silicone under pressure.

Design
We combined the Aeros intake tube and Sidewinder into one piece, the result is the Bigmouth™ sporting a 3.00″ inside diameter! By designing one component, we are able to remove the diameter restrictions of being modular and increase the inside diameter to 3.00″ from the MAF housing to the turbo connection (2″ OE or 4″ GT). There is NO relocating or moving of the battery or ECU. The Bigmouth™ is compatible with the Aeros SI or ID300 MAF housings. For even more power, check out the Full3 Aeros ID325.

Stealth Clamps™
Every Bigmouth™ includes stainless steel SURE Stealth Clamps™ that feature an inner lining that protects the silicone during tightening.

Heavy Duty Couplers
The recirculation coupler is made of high quality, heavy wall 6061-T6 aluminum. The 6061-T6 aluminum is anodized black and is corrosion resistant. The thick wall allows for clamps to be tightened to a degree far exceeding what the stock turbo inlet or other similar products can handle.
