Agency Power BMW 135i 335i Turbo Inlet Pipe with Blow Off Valve Kit NOW
Available!:

The powder coated aluminum inlet pipe replaces the entire flimsy OEM plastic piece with a larger diameter, kept all the way through. The larger diameter inlet pipe improves air flow and also gains power. The Agency Power blow off valve can be configured to vent 50% of the air back into the intake and 50% out to atmosphere for that desired WHOOOSH sound or 100% recirculated just like the factory setup for quiet operation.  The BOV can also be vented 100% to atmosphere for that desired turbocharged  car sound.

Note: The attached graph is of a 335i with intake, downpipe, intercooler and flash. The Agency Power Inlet and BOV Kit helped maintain a constant boost which gained 50rwhp and 40 ft. lbs.  The need for a stronger BOV and Inlet Pipe becomes more evident at higher boost levels.

This kit is available in all silver, all black, all red, or all blue and includes black silicone couplers and clamps.  Limited Lifetime Warranty.
