ok so i wanted to put cone filter on car without the cai tube cause well i just dont have it lol.well i unpluged the maf sensor and started the car up to see what it would sound like wiht the filter since it isnt going to work ..lemme tell ya it sounded freakn awesome! had a whistle and whine to it and everything.one thing tho runnin it like that with maf sensor unhooked made engine light come on lol
i know i can just disconnect the battery to reset ecu but i wanna know if you can really run car without MAF sensor for any extended amount of time without damaging the engine?good luck anwering this one lol

no, you can't. But if you liekt hat whistle, reaattach the MAF, then drill another hole in the tube, you'll get the same whistle, but still have the MAF

yea its no biggy i just disconnected negative ground on battery and reset the check engine light and bought a matrix adapter to hook up my cone filter with the mass air flow sensor ...runs awesome and sounds great ...picked up at least 1 1/2 to 2 hp but you can tell more from the torque! thanks for the replys.

Having another hole in your intake after the MAF is never a good idea. It is metered air being tampered with, which can make your car run lean or rich. Usually if you losing air the engine will richin up, so the ECU will lean the car. I think my intake has a hole and it has been screwing things up from the get-go. Having your MAF unplugged also wont let your car go into closed loop, so your load calculation gets messed up in the ECU. Leave the MAF plugged in, and get rid of the air leak.
