I dont get it...the old one fit or not? If it fit get another OEM filter until you can find another source. But if the OEM didnt fit right either, why not make it the delaerships problem? Bring it to thier attention.
And this is the part I dont get...all the K&N bashing around here, but the concensous is DUCT IT! Theres something seriously wrong with this guys intake...it wont close/seal? Thats a problem, are there similar reports in the Titan forums?
Or have you considered an aftermarket intake? Especially if your going to be changing filter every 6k.
Ive got a couple of friends with Titans...makes me curious now as thier both mechanically challenged.
