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)

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.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
