Aftermarket Heat Exchanger options

[ebristol]

Hey guys,

I have a stock cobra heat exchanger on my ION RL that just made out with a stone.





I know I can patch it and be ok but I thought I would take the opportunity to upgrade to something bigger.

My question is what have you guys had the most success with?

Larger capacity units



Or Dual pass units



Thanks for your input.
