[PLF69]

I had a track day last Saturday with Wagner stage 1 comp and I was really surprised how the temps can drop so fast between pulls/straights.

My engine is fully stock expect afe air filter.

Ultimately a similar size bar and plate can absorb more heat but I think the tube and fin is the winner for avoiding heat soaking and dissipate heat between sessions.

Depends on usage, on my M235i I dragged race a huge bar and plate was ideal.
