Great quality and possible my next intake as my 3" custom intake is not tuneable with the MAF scaling.
Im sure their dyno day read a 12hp increase. But their sheet if you look closely, their ZZP intake dyno was done 1st with a cold engine bay, Then the stock was swapped back on and re dyno'ed 9 minutes later in a heat soaked engine bay.
Little trick that pumps out awesome dyno sheets XD
Everyone does it. ZZP cant be singled out here
