Which ones to get IT16, IT20, 22, 24 ????
anyone run these and how do you like them

[L8 APEX]

I like them a lot but have also had good luck with Tr-6s. It-20's for stock, 24's over 4#'s or NOS.

I'm running IT-20s :cool:

16's for stock
20's for stock-2lbs of boost over stock
22's for 4-6lbs over stock/small shot of nitrous
24's for excessive boost and/or nitrous (very cold plug)

I have run IT24s with my #6 for about 9000 miles. They work great!
