A: On a technical standpoint, aluminum would be a little more subject the heat because it is metal, but, it is thin walled tubing, and would also dissipate the heat much faster as air is moving. The issue with a plastic intake, while it takes just as much time to heat up, it takes a considerable amount more time to dissipate that heat build up, also known

Works like a supplement
If you use it and see a difference, you will blame it on this cleaner, if not, you will say the product does not work. Exactly like your weight loss supplements! Who knows what this stuff does, but it may do something. Or maybe it does not.

Used to clean an O2 sensor
Seems to have resolved an issue with a wavering idle for my 89 Mercedes 300e with 468,000 miles.

Worked like a charm! Used as directed, it cleared the P0420 & P0430 codes that were coming up on my OBD II scanner after a complete engine swap. Definitely recommend this product.
