Review on 🚗 K&N Cold Air Intake Kit for 2012-2015 Toyota Tacoma, 4.0L V6: Enhance Performance, Boost Horsepower, 63-9037 by Chris Horton

I like the final fit and performance, but this air intake MUST be adjusted. The secondary air pump can cause problems. Secondary Air Pump Issues: - Poorly designed mounting brackets - OEM wiring harness is too short, you MUST re-route the wiring harness. The wiring harness does not go through the air box - The hose of the air pump line is too long, you must shorten the hose when using it to avoid kinks - If you look at other people's posted photos, you will find that the air hose is kinked. Also, you may need to purchase a torx socket as the engine cover studs are torx sockets. I'm very meticulous when I work on my truck, so everything has to be perfect. I think if you don't mind pulling the wires and kinking the air hoses it's pretty easy.
