offroadsubaruguy Posted July 30, 2007 Share Posted July 30, 2007 so heres the deal, i have an intake on my 90 legacy. it comes with a cone filter.... so heres the question, i also have a modified airbox from my durango that will fit the intake, so should i run that or should i run the cone filter and make a seperator to keep the warm engine bay air out of the intake?

porcupine73 Posted July 30, 2007 Share Posted July 30, 2007 Whichever you do, if that vehicle has a MAF, the diameter of the intake tube that the MAF is in must remain the same as original. Otherwise MAF reading will be incorrect. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted July 31, 2007 Share Posted July 31, 2007 The MAF is a separate unit, and shouldn't be modified...... Personally, I'd go with the airbox. The cone filters can cause issues with sucking hot/turbulent air, and the MAF sensor not reading the air flow correctly. Quote Link to comment Share on other sites More sharing options...
nipper Posted July 31, 2007 Share Posted July 31, 2007 airbox, and no oil soaked filters. Those can damage the MAF. nipper Quote Link to comment Share on other sites More sharing options...
xrturbo Posted August 1, 2007 Share Posted August 1, 2007 Double that on the oiled filters. Everytime I have ever tried an oiled type air filter it started to run like crap and wound up needing another MAF. Quote Link to comment Share on other sites More sharing options...
