STM Intake Kit for Stock MAF Evo 8/9

STM Tuned Inc.



We price match!

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.

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.

Perfect fitment for my evo 8

This intake kit fit perfectly on my evo 8 and looks amazing. Everything seems like its gona flow more direct compared to my old one. Would definitely recommend. I swap my filter for the vibrant 4.5inch and maf sensor adapter works perfectly. No more blox filters needed.

Really good, love stm products

T.K. (Centreville, VA, US)

Great product and shipping was very quick! These vehicles should have been manufactured with an intake system similar to this out of the factory as you can hear the turbo breathing as it should! No issue with the install, other than having to cut a couple of inches off the existing rubber hose connecting the upper inter cooler pipe to the bypass valve to fit.

*Install note: You will need a rubber hose on hand to connect the bypass valve to the intake pipe, so buy one at your local auto parts store beforehand.
