So while changing the oil today, I noticed my filter needs a good cleaning.

My only question is why everyone says not to use the AFE cleaning kit?

Is it a bad oil product? Cleaner? Applicator?

If it matters it's a PG7 filter.

Thanks In Advance

You can get the K&n cleaner kit at all the parts houses. That is why my pg7 is k&n red. If i could of bought the afe stuff locally i would have.

 

I used the AFE cleaning kit to clean my standard filter. Kind of a pain in the butt. I have a second Pro-Guard 7 filter, so I was in no hurry. I had to use the cleaner twice in a bucket to get it half azz clean. Let it dry 3 or 4 days, then light spray with oil, let dry for a day or two another light oiling until it looked even.

 

I use the K&N cleaner and oil. As mentioned by Kelley15 easy to buy just about anywhere. Also the k&n cleaner seems to do a better job of cleaning the filter and the oil sprays out in more of a mist, unlike the afe stuff that sprayed out in a stream. Makes it a lot easier to recoat the filter without applying too much oil...and the k&n stuff is red so you know if you missed any spots.

 

I don't K&N oil is the right formula for the AFE...too much of it gets sucked through the filter into the intake tube IMHO.

 

don't use k&n products on the pg-7...i made the mistake of using the oil once and a bunch got sucked through the filter and it slimed up my entire downtube...as well as the air sensor...then my truck threw a code on me..major pain to take everything apart and degrease it...

 

So what does everyone recomend?

Is the AFE cleaning kit OK to use? Is everyone just saying not to use it, well because...?

 

From what I've read, the AFE oil won't interfer with the air sensor the way the K&N oil will. I spray mine with Simple Green and wash it that way and use the AFE oil. First cleaning kit I had the oil was in a pump spray bottle. Kind of a pain to spray the filter. The second kit had the oil in an aerosol can. Whole lot easier.

 

A quick splash of gasoline...followed by Simple Green soak for a while..hours...then several clean water rinses WAS the best for me...
