I had the 12mm on my V6. Too be honest, I wouldn't do it. Barely noticed any real improvement, maybe slightly in the midrange.

Waste of time and money. Unless you're boosting it forget any mods on the V6 and save for a V8.

The 24mm won't fit our Engine. From what I understand it raises the intake manifold too high to fit under the firewall. Only fits the LTT.
