When installing a k&n cold air intake when do you allocate the MAF sensor?

You shouldn't have to relocate the MAF. Also make sure not to over oil the filter, as it will gunk up the MAF.

ok, well if you have the one with the intake tube, then you put it between the tube and the filter wall.
Here's the instructions.

Awesome thanks a lot man, I got it on today!
But I'm considering taking of the heat sheild because I don't think it's the right fit, do you think taking of the heat sheild would be okay?

The heat shield is important because it keeps the hot engine air away from your intake. Without it you will lose horsepower and get lower mpg.

Okay good to know, I might need to get a different heat sheild then. Thanks again!

Do you notice any difference after installing it? I thought about installing one of these for my 325i in the summer and never got around to it

Well I took it for a spin just down the road and back. I cleaned my MAF sensor at the same time and I had more throttle response for sure and a bit more power. And it sounds damn killer! Well worth it man, just make sure that the kit you get has the right heat shield, the one I got has no hole for air hose coming from te center of the grill.

Lol, I sold mine because you just lose power in the summer. The car will bog down on a warm day, especially noticeable when you're sitting in traffic.

Read your intake air temperature with the stock intake, and then the K&N.
Stock will read lower (Hint: colder air is better)


All you're paying for is sound. That's it!

Your kit should have come with 2 different plates for the heatshield.
One of them has the hole stamped through it, the other doesn't.
