Awesome

Awesome product by HKS. Easy bolt on install and comes with extra hose length/ zip ties if needed. Looks good under the hood and sounds great.

HKS BOV

Decided to go with the HKS cause I love the sound but part DOES NOT come with the recirculated hose as shown in one of the product pictures so you can not run this on stock you will need a tune. I ran the hks on stock psi for a couple of days an plugged my bypass with the part provided and gave little to no atmosphere release and car was running rough and was forced to return to stock until tune. Overall I'd rate this 8 - 10 because it did not come with the recirculating hose to run on stock tune and didn't live up to atmosphere sound of previous HKS BOV's
