RK Autowerks Carbon Fiber Intakes (CAI)
Ordered a set of these and really looking forward to putting them on. That being said, i just can't wrap my head around trusting no water gets in these.
Has anyone put a pre-filter on theirs? If so, what brand and size? The filters RK ships are no longer the K&N cotton filters, and the new ones are unmarked. I measured, but it doesn't look like any of the Injen pre-filters really match up on size.
Any experience/help would be greatly appreciated!
