LX 4 CYl, Sorry for not answering that part of your question,, My bad on that part,,Useing a remote cooler and filter might sound like a good idea,, But My concern would be, if you had a warranty problem useing the remote cooler/filter.. I would have to void your warranty, due to the possible restriction( yeah I know they claim, no restriction)Buyer beware..If I believed every aftermarket HP claim, I would have a 1000 HP Mustang for $500,, ditto for the Import crowd.
