What is the best bang for your buck cold air intake for a 2004 H2? And are they worth it for mileage or performance gains?

 

best bang for the buck is leave the stock one alone get a new filter if needed. it will out filter and out perform any aftermarket units.
on the plus side it actually pulls in outside air as opposed to hot engine bay air.

 

Thanks

 

CAIs are not worth anything really. Especially in newer vehicles the stock air delivery systems are typically tuned specifically for the engine. The only reason I put one on my H2 was because the factory air filters are a joke in price. I run an Air Doc tube customized to fit my Volant box which houses a Volant oiled filter and prefilter

 

I appreciate the info, thank you
