    Hello all, what do u guys think about pannel filters, are they worth fitting performance ones or keeping standard paper one?
    I had a itg one fitted but ended up taking it out cos of it being a oiled filter and didn't want to cause damage to the maf sensor.

    Thanks James

    Personally I would stick with an OEM one-have heard they're as good as any performance filter and cheaper too as long as its kept clean.

    I'd just pop the ITG one back in, personally, they're great filters.

    A lot of nonsense is spouted about oiled filters contaminating MAFs and the like - in not one single properly held test has it ever been shown that a correctly oiled filter has contaminated a MAF sensor.

    For example, what do the BMW BTCC cars use? Oiled Pipercross filters. Some very experienced tuners and racers all over the world use oiled filters with MAF-equipped cars without issues.

    I've personally used oiled filters on numerous cars with MAF sensors over the years, and never once had a problem even after thousands of miles. I've got a Pipercross kit on mine at the moment - no problems. Had a K&N on it before - no problems. When the MAF on my 328 expired, it did so having previously had nothing but the standard paper filter fitted!

    Put too much oil (like admittedly most people do!) on a filter when cleaning though, and sure, it'll stuff your MAF eventually. If your filter looks even slightly oily or shiny, it's too much. A very, very fine dusting of oil is all that's required.

    MAF sensors are more fragile than a lot of things, but they're a lot tougher than a lot of people give them credit for! If they could be killed in moments by the tiniest of whiffs of contaminant, then even with a paper filter fitted you'd be replacing MAFs more often than you changed the oil rather than at 100k+ mile intervals.

    After you clean them. Clean with the specified cleaning stuff, let it dry, spray a very thin but even mist of oil onto it, let dry again (which is the bit most people seem to miss out) and then refit.
