K&N Filters bad for ls1's???
 

ok this might sound stupid. But the other day when I took in my car to the dealership because the check engine light came on. The service advisor asked me if I had a k&n air filter for my car...and I said no. The reasoning behind all that is because he said that the lubricating oil for the filters make the mass airflow sensors go bad. I never heard of that or experienced that so I don't know. What's everbodies opinion on that....i think it's bull****

It is not BS, it can and does happen if the filter is recharged improperly. I would not recommend a K&N anyways. They offer no real HP gain and do NOT filter as well as paper.

I'd say that's actually pretty common. A lot of people "over oil" their filters, but they filter just fine.

Filter fine is possibly true, still not as good as paper. Check out http://www.bobistheoilguy.com/airfilter/airtest1.htm

Judging from the "scientifically conducted" test (put a piece of fabric behind the air filter and snap a photo of it afterward) it seems that all the air filters tested suck equally.

lol, maybe so.. But for the lack of any real gains, I choose not to chance it.. I'll stick with paper..

Re: K&N Filters bad for ls1's???
 

lol well, yeah. Anyone who thinks K&N is good for 5rwhp is a rookie---- or running a 1000+rwhp.

Paper filters will work just as fine and are 1/4 of the price of a K&N

;)

Looks like i won't bother getting a k&N either.

As for it damaging the wires on mass sensor, that happens. I used to clean my old car equipped with a K&N every now and then with electric contact cleaner and a cotton swap (gotta be real careful). Seemed to help.

So by the time you buy 4 filters the K&N is paid for.

Check out Holley Powershots and other filters too.

The fact still remains there is no power to be had from an air filter.

Re: K&N Filters bad for ls1's???
 

Yup, don't look at filters as a performance mod and you'll be much happier.

I bought the Fram Air Hog for my 98. I don't think it was a hp gainer, but it couldn't hurt. My filter needed replacing anyway so I decided to get one like this and not have to replace it anymore.

Re: K&N Filters bad for ls1's???
 

When i bought my ls1 it had a k&n in it which was over oiled. My maf was covered in oil and dust. I will be putting a paper filter back in.

We did an airflow test with the usual paper filter that people use and a K@N. This is no lie but the K@N aloud way more air flow. That much increased airflow should alow like a couple more HP.
