Heatshield Products HP Heatshield Mat Reviews


Great Quality, Easy to use

Reviewed By Matt D (Encino, CA) Reviewed for a 2001 Audi A4 —4/3/2014 12:42 PM

The HP mat does a great job repelling radiant heat from my turbocharger and exhaust system from being absorbed by my intake system. Keeps my heat shield running cool and reducing heat soak.

K&N filter was great

Reviewed By Matt C (Milpitas, CA) Reviewed for a 1982 Nissan 280ZX —2/22/2015 9:15 AM

I have ordered in the past and this one didn't disappoint. the best part, besides the great red color, is that you can feel the difference in the sound and the response of the engine.
