I got bored at work today so I bored out my MAF. actually I got an extra from an internet junk yard for $55 shipped from a 99 sentra se-r. I opened the mouth up so the air should flow through better. but I really diidn't change the overall size that much. maybe a mm or two. tommorro I plan to high polish the inside so the air will shoot through and paint the outside with high temp black to keep it a little cooler. I hope to be getting my reducers monday by the tracking # so I should put the bored MAF & homemade CAI mid pipe in some time next week. I will also be adding the how to for both on my web site some time next week after all the pictures are taken. Hope I get a horse power or two out of all this but I'll settle for a good looking engine.
