Hi all

Just wondering if its ok to lightly oil a green cotton air filter?

Car is a jdm v3 sti 1997

It is due a service

 

Going back many years now, but this was a big no as the oil could contaminate the MAF.

 

the k and n ones , a very light oiling on just the correct side of the filter was thought to be ok , it was said people were oiling the wrong side and putting too much oil on it , and that’s what caused the maf issues , i suppose it’s weigh up the cost of a maf v higher wear on the engine , there are good filters out there that don’t need oiling , there was a test done the standard sti paper filter v the k and n panel filter and there was nothing in it , it’s more of a money saving exercise so you wash it rather than buy new each time , the filters need washing around 10 to 20 k miles not the suggested mileage

 

There is no mention of oil on the green filter website (apart from pre-oiled in a tag box) which is 7/8 years old and appears to be linked to Auto Inparts but most of the links from the page do not work.

Maybe contact Auto Inparts and enquire about it.

 

Thanks Don and everyone else. Appreciate the i out. I have oiled the filter but will let it dry at room temperature for a month before fitting. That way any residue is hopefully removed
