STM Intake Kit for Stock MAF Evo 8/9

STM Intake Kit for Stock MAF Evo 8/9

The STM stock MAF intake pipe kit is designed for your Evo 8/9 running the factory MAF sensor and will adapt to any stock-style blow off valve. The pipe will free up power and let your 4G63 breathe while giving your intake a bit more aggressive sound.

• A K&N breather filter is also included for your valve cover.
• Fits all stock turbo inlets and any aftermarket with 2.5" compressor.

Vehicle Fitment:
2003-2006 Mitsubishi Lancer Evolution VIII IX
• Fits both ACD and non-ACD models
• For use with the stock MAF
• Not confirmed to fit with the stock upper IC pipe
• Recommended for use with STM UICP as pictured

What's the Bung For?
Adding the -10AN bung on the underside of the pipe is allows you to use the STM Sealed Catch Can which vents from the can to the intake pipe.

Includes:
(1) STM Intake Pipe
(1) STM 4.5" Air Filter (STM-4260)
(1) Vibrant MAF Adapter & Gasket (1995)
(1) K&N Valve Cover Breather Filter (62-2470)
(1) STM Coupler 2.5" - 3"
(1) STM Coupler 3" - 3.25"
(1) Worm Clamp 2.5" (62017)
(2) Worm Clamp 3" (62020)
(1) Worm Clamp 3.25" (62021)
(4) M6 x 25 Stainless Button-Head Allen Bolts
(4) M6 Stainless Lock Washers
(4) M6 Stainless Nuts

Results:
On a stock Evo 8, we gained +13 HP on our Mustang Dyno from 4,000 rpm all the way through... right where you want it!

Gains can be expected to be higher with more air flow and boost, of course.
