K&N air filters......yay or nay ?

[Mc Tool]

I have put them on a lot of motors over the years ....believing they were a good thing but I just read on google that they mess up mass airflow sensors , dont filter as well as a paper filter and dont add hp ( I knew that they dont add hp).
I just bought another one and was googling to make sure its pre-oiled ( it is ) cos the last one wasnt but this one looks like it is

It's a fine line on them for too little oil and they do not filter properly, or too much oil and they foul the MAF

Yeah ,thats it , this is the 1st car I have intended to fit one to with a MAF ....everything else was carbed. And , to oil them properly takes a while for the oil to wick over the whole filter if you dont drench it . The last paper ( Ryco ) filter has lasted 60,000kms and still looks ok ....once I got all the bugs and leaves out of it

I use a "disposable" K&N in my older Tacoma - no issues. It actually depends on your area, driving and amount of use..
