I purchased this system after trying one of the cheap Chinese knock-offs. I should have purchased this from the start. Quality is obviously night and day. Overall easy to install. Looks good in the engine bay and the plastic seems to dissipate heat better than the metal tube I had previously. Small increase in power but nothing substantial. I have four other intake brands on various vehicles but this is the most affordable option and has similar results. Buy It
Blackhawk Intake System on 2013 Denali
The system itself fits very well and the appearance looks like it belongs under the hood. I gave 4 stars verses 5 on Overall Rating and Ease of Installation not due to the unit but the vague instructions. Each step does have a picture but simply stating perform that operation without detailing hardware etc does have its drawbacks. I referred to the exploded view to determine correct locations.
Volant powercore cai
Volant CAI with power core filter was a perfect fit on my 2002 Yukon, no induction noise has been noticed over the stock air box. The construction and appearance are top notch for the cost of the unit. Cleans up the under hood appearance and time will tell if drive ability or economy is improved. I like it and would recommend it over other cai products on quality alone.
