Great product.
Great purchase. Product works as intended. I have been checking mine every thousand miles or so and I get about 2 ounces of oil vapor each time. Insulation was a little tricky, but once I figured it out, I’ll install the next one on my next Yukon very easily.

Worlds really good
Installed this catch can a week ago and drove my 2015 Silverado 5.3 1500, 4 hours and it’s caught a good amount of oil in it. Easy to install and would recommend putting a cover on the hose cause it does tend to get pretty hot throughout the ride but other than that no issues and works really good!!!

Good for the money
Works for the 4.3 v6 as well. Plug and play. Smaller than I was expecting though

Great addition to vehicles
Second one of these I bought. One for a 2018 Silverado , one for a 2020 Tahoe. Easy to install. No leaks.

Easy install
Easy install, perfect fit, took some 20 mins to do. Had to remove the intake box to access the PCV valve and remove the existing hose. Looks solid, and priced right.

Its catching waste.
Seams to work well. Waste is in the can only after 200 miles of service. Install was fairly simple.

Shoulda came with directions
I have a 2014 5.3 Chevy Silverado while I have this installed I’m not sure if I have it installed correctly. Due to the fact I’m not sure if the pcv is supposed to go to the inlet our outlet part, wish they had better directions, however it does work.

No instructions on the box. I’m not sure where I connect the in and out sides of the can hoses to my engine
