Recently installed a set of K&N intakes and the silver color wasn't doing it for me. I came across VHT Wrinkle paint and thought I would give it a try. Its good to 350 F so it should have no issues in the engine bay. A similar wrinkle style coating is available in powder coat, but I wanted a nice easy DIY solution.
I think it came out great, it's a really clean almost OEM look to it with the textured surface, it's really durable as well, smacked it with a wrench that slipped a couple times putting it on and no damage at all.
I would recommend the oven fast cure listed on the can, otherwise it does take a long time to cure fully.
I did mask off the area that engages with the couplers, MAF's and the filters to provide a smooth sealing surface.
Really pleased with the look.
(engine bay is a little dusty from winter storage)
