Has anyone used K&N filters in your cars?
I have one in my FiST. Had one in my 2011 SES. Have one in my 1997 Ranger STX.
I googled it and boy is there a lot of negativity about them.. I threw one in my car today
I had a K&N filter in my 2011 Fiesta for about 90 days until I got a cold air intake for it that came with a dry flow filter. The only "problem" that I'm aware of with K&N filter is when people OVER OIL them and the oil gets onto the MAF and ruins it. Other than that they are fine. I got a Green filter from FSWERKS for my Fiesta ST which is similar to K&N.
...and some local guy bought his K&N off of him awaiting Cobbs intake. Lol
So why all the bad articles on them?
Do we have to worry about MAF fouling? I didn't think we had a MAF. Probably not going to run a K&N. Have done it on past vehicles and don't like worrying over maintaining it.
Name something there is not a lot of negative comments about.
Other than the FiST of course!!
lol too funny I saw that ...
Just trying to find out about the K&N filters that all
K&N filters (as well as the Green brand) do flow better. At the end of the day you may pick up 2HP with this filter. The problem with them is that they let in a lot more dirt. if you plan on keeping your car for a long time they are not the thing to get.
Well at least 6 yrs..)
I just got a K&N and I'm just going to run it during events (not RallyCross ones). I'll swap the paper one back in for driving through the demolition/construction zone known as Our Nation's Capital.
The whizzing intake sound toned down after the change, what that means I dont have a clue.
