Now that I saw what the airbox mod is all about, I will go ahead and finish my ABS insulated plastic box to make a thru cold air intake, not like those you find on ebay that still need a better design.
I have a lot of knowledge on NA and force induction engines, and I do a lot of custom work, I'm not a big fan of magazine performance parts
Regarding the test without the air filter, I know how easilly the can be damage that's why I only drove maybe .5 miles to test the difference, I already cleaned the MAF sensor.
