Today I just picked up my 1992 Accord from the shop. Had all four engine mounts replaced, timing adjusted, vacuum checked for leaks, AC serviced. A few weeks ago I had the timing belt, water pump, tensioner etc. replaced as well as distributer, coil and fuel filter. Also did 2X drain/fills (so far) with Maxlife ATF. At 150K miles it drives great and engine sounds like new.
I just bought it recently, and it has a K&N sticker on the air filter box cover. I'll check it today, and have a replacement regular filter ready to go if it's actually a K&N.
