Flowmaster 615135D 12-18, Wrangler Jk, 3.6L, Performance Air Intake

This is an exceptional product. Made the jeep sound like it was going to take flight. You can feel the difference and there is a performance upgrade. I coupled this with a throttle controller. Very happy with the results.

Easy install

Easy to install. Looks great.

I bought the kit with the dry filter with the pre-filter. Filter assembly looks solid. The manifold looked terrible. Stainless steel hardware is solid. The moulding was bubbled all over and the fitment of the pcv hose into the manifold can never be rotated in the right direction. So quality was suspect. Installed anyway, sound is killer. That intake at high gears turns into a growl. Much better than stock intake. that growl just means more gas so when you hear it forget the mpg savings. I did take it for a highway spin and I can confirm +3mpg on the highway with heavy 55 pound tires. In the city the sound is too addictive so probably -1mpg city driving. Power wise i think the advertised 4% sounds about right. I don't know about the high end HP but in between the gears there are definitely less down shifting so torque is definitely up. Also on inclines there is "more go". So not a huge power difference but something. I would not buy for the HP+ but the sound and highway milage yeah. I'd be looking at a different kit with a pre filter. Or be prepared to custom build an intake tube which is what I'm going to do. Only reason they got some stars is the seller offered a return or a discount. So the stars are for the seller not the manufacturer.
