yeah that's why I really didn't like the TRD one which ended up with so much excess oil. I'd definitely add some kind of sprayer if I did it again.
Yes, Sprey, there's much documented debate about whether the oil can foul the MAF sensor. I think I even recall seeing a video on K&N's site to disprove that assertion. But many have also said if that does happen, it's pretty easy to clean the sensor.
Even so, once I saw the nano technology dry air filter from Amsoil, and that it's used by the military in the Abrahms tank, I decided it was the one for us. Sounds like the sales guy has me hypnotized I guess.
Too bad they don't make one to fit the VX....so I'll stick with the Green filter for the VX until either the rubber seals rot away (thanks Lisa) or something better and easier comes along.
