Go Fast Bits TMS Respons Blow Off Valve Kit - EVO 8/9/X

Product Description

This blow off valve is ideal if you want the loud swoosh without your car stalling out or running rich!

By utilizing a unique air diverting system, you can control exactly how much air you dump to the atmosphere for noise, or the inlet for silence. By sending the vented air back to the inlet (rather than muffling it), there is no restriction and the valve still operates at maximum efficiency.

For cars with sensitive air flow meters such as the EVO, the valve can be tuned to vent just enough air back to the inlet to prevent backfiring while still giving the loudest possible blow-off noise. This BOV is fully adjustable by the flip of your wrist.

TMS - Turbo Management System - Don't throw your BOOST away - INCREASE IT BY 40%. GFB's Turbo Management System (TMS) parts offer multiple performance benefits over factory diverter valves.

Factory diverter valves are commonly known to leak or fail, especially with age or higher boost levels. A GFB TMS will hold as much boost as you can throw at it, 24/7 - No frequent re-builds or replacement required.

BETTER RESPONSE Through reduced turbo lag - The GFB TMS is designed specifically to minimize lag - tests show that it can return the engine to peak boost up to 30% faster than a factory diverter when shifting gears, while delivering up to 40% more transitional boost (see GFB brochure)

BETTER DRIVEABILITY - Smoother than stock. Factory diverters tend to operate fully open or fully shut. This can cause annoying surging at freeway speeds, requiring constant throttle corrections to hold steady speed. The GFB TMS completely eliminates this problem, making the car smoother to drive.

GET THE SOUND - OR NOT - It's your choice! Want noise? GFB patented Respons succeeds where others have failed! By adjusting the venting ratio of atmosphere/recirc, you CAN acheive a sound WITHOUT throwing a CEL, running rich, stalling using more fuel or causing other problems commonly associated with atmo-venting valves.

TECH TIP: This is a 100% bolt on BOV for your 03+ EVO, no expensive flanges are required for installation. Installation is very easy and will only take 10 minutes and can be done in your driveway. The blow off valve provides a deep whoosh under heavy boost and is fully adjustable with the flip of your wrist.

Fits: Mitsubishi Lancer Evolution 8, 9, X / Lancer Ralliart 2.0T
