Re: cold air intake on EL
What you described can be done, but it won't make a scrap of difference to even a mildly modified engine.
Just go and grab a snorkel from an EF XR8 from Ford, they are around $40 or so.
4L I6, naturally aspirated producing 173.5rwkw.
14.410 @ 96.49mph with street radials.
What's that?..... Did I hear you say TQE power?
