Drivetrain In Praise of the MCS Air Box
Yeah! closed off all the holes I had drilled ( WEBB Mod ) in cowl partition from other CAI system I made except for the one where the box base seals with it. That is enlarged to match the 2"+ PVC pipe with rubber seal to seal with cowl partition. The Alta intake hose is matched in size to a SS velocity stack which sits in a neoprene gasket so no dirt or hot air can get into the clean side of the air box top. The stack would slip over the stock nipple before I cut it out of the way to fit this into the top.
Has anyone else noticed that the stock air box is also used to cool the ECU?
There are discreet vents in the ECU holder that pull air around the ECU and into the base.

I can't say that I agree with you.
After this free mod : https://www.northamericanmotoring.co...7&page=1&pp=25 I like the fact that I still spent $0 on an intake.
Some things that I dont like about the stock airbox:
1. Flow. My 05 MCS died at 5500 w/ the stock airbox. With my free mod it now pulls strong all the way to redline+
2. Sound. If you like the sound of the stock airbox, you'll love the sound of my mod (or an aftermarket one).
I'm glad that you're amped about the stock box, but I for one found it rather dull.

Paper is an excellent filter medium and is enhanced further will an application of oil; however, the stock panel filter has too much oil on it so it becomes saturated with dirt quickly. The downside is the A/F mixture becomes richer when air flow is blocked along with potential contaminates. Wix makes a replacement paper panel filter that has less oil on it so service life should be longer (I replaced the stock elements at about 4,000 miles of use). Another plus is an increase in the number of pleats to 80 resulting in greater surface area which should equate to more flow. Even more good news, NAPA filters are made by Wix so getting one should be easier than a trip to the dealership; MCS #2800, Cooper #2799.

for frugal buyers, uni also makes a foam flat panel replacement filter which is less than half the cost of the itg. you can get the uni oil at motorcycle shops.
k-huevo thanks for the update
