That's odd.... I have personally used the 04 in the 05 air box and it does fit correctly....redrocketgto said:The only green filter number (2400)I could find is for the 04 goat.The K&N filter numbers between the 04 and 05 goat are different.So I am thinking you may be letting more into your intake plennum than just air if the filter box is not the same size.
:agreeredrocketgto said:Maybe it does fit ok and if it does,why would the filter numbers be different?GTO dealer I dont think I would want to take the chance of it not fitting properly.Since I am in S.Florida,the land of sand,sucking in fine particles of sand around the filter sort of worries me.
Interesting point, I actually looke at a customers GTO that we installed an 04 filter in (his is 05 obviously..) and it did fit perfectly! :cheersPennsylvania Goat said:Unless the laws of physics were voided that day, my green filter fit perfectly and sealed just like a stock filter in my '05.
I believe what he is trying to point out are the specifications of the 2 filters (regardless of the manufacturer). Unless K&N has it wrong, it is a valid comparison.Pennsylvania Goat said:The Green Filter is not made by K&N. Seems like apples and oranges to me here. Am I wrong? (Wouldnt be the first time. )
I had a hard time finding the 05 GTO K&N replacement air filter - most vendors just carry the 04 online , quess you could call , but this is an online arena ... Ordered with free ground from these guys :redrocketgto said:K&N has released a part number for the 05 goat air filter for those of you that want to keep your car close to stock.(#33-2314).This is not the same part number as the 04 goat.
BigNick said:Perhaps their rubber sealing pieces are flexible enough to compress by 5mm to fit into the slightly different '04 filter box.
