I have a '99 Boxster. I purchased online an EVO "Quick Flow" kit which uses an OE style flat K&N oiled filter, and had my dealer install it at about 60,000 miles. Sounded great and I did sense slightly better throttle response. After about 8000 trouble free miles the "check engine light" came on. The dealer diagnosed that oil from the filter had fouled the MAF sensor and it need to be replaced. Since they had replaced the MAF sensor at 58,000 mile prior to them installing the EVO kit, they did agree to replace the MAF sensor at no charge ONLY if I agreed to use an OE filter instead of the the oiled filter that came with the kit. Seemed fair to me so I agreed and they only charged me for the new OE filter, no labor labor or other parts. Still has the great sound and seems to be performing great so I think I'll stay with the OE filter rather than risk fouling the MAF sensor again and this time have to pick up the bill!
