Default K&N oil filter - spraying oil on the filter

What's the consequence of not spraying enough oil on the filter? I've had bad experience first time (too much oil) I sprayed oil on the filter, so I am trying not to put too much oil this time.

What could be the implication of putting too little (or excessive amount) oil on the filter? I understand that MAF sensor can get dirty.

Use too much oil and some can get on your MAF (which you can clean). Too little and the filter won't be as effective.

A friend used a KN on his Mustang and had problems with oil fouling his maf. I used one for years in my Mustang and had no problems. Haven't put one in my WRX. Just don't use too much oil. Let the oil dry thouroughly before installing. At least several hours in warm area.

Too little oil will compromise the filtering capability, too much will increase the possibility of contaminating the MAF sensor. The MAF sensor can be cleaned, and you can pull excess oil out of the filter by letting it sit for a while on some old newspaper. The excess oil will be absorbed by the paper.

K&N have good detailed instructions on how to oil the filters in their cleaning kit and last I looked the same info was on their web site.
