Hey, i checked on that "Do I need Intake Port Matched"
The Intake is bigger than stock 52mm TRUE
it is actually about 53-54mm, i measured it, so no you do not have to get it ported
but i did mention if you go 55 OR Bigger you would prob. want that ported, or if you want it for later on, your going to pay more than $25 bucs believe me.
However, It is an OPTION so yes i could get yours to 55mm for $75
but it's not goin to hurt to get the intake done, 1 - 2mm difference,
thats up too you, doesn't sound like alot, but thats the same as saying whats the difference between 55-57mm soo it's all up to your preference.
