So I saw a bunch of people on here who cleaned the MAF with good results. I decided @ 130k miles and a K&N cone filter on for the past 100k miles it was time to clean it. All I can say is it drives like a brand new car. It used to be alittle sluggish and would downshift alot going up hills, well that's all in the past now. Additionally, I think my gas mileage has increased judging by the needle and current tripometer. BTW, 5.99 @ the local pepboys.

really? i heard this wasnt safe on the 03's maf thou?

I tried that on my '00 and didn't notice any difference. It still hiccups around 3500rpm with some hesitation. Previous owner replaced the MAF at 68k miles with 112k now, so it probably just needs replacing again.

I cleaned mine not too long ago, and still works like a charm.

what year is your maxima??? did u notice any type of power gains, did it make any hesitation problems go away?

It's an 03.

I do not nor have not had any hesitaion, so I cannot answer that question with any viable results.

There was no noticeable difference in performance.

I think ill give this MAF cleaner a try, my car still has the original MAF (182k miles) and probably has never been cleaned.
