ESUPPORT Universal 12mm Mini Blue Cone Cold Air Intake Filter Turbo Vent Breather Car

I used this to fit right over the valve cover vent that returns to the carb on a Harbor Freight Predator 212 cc engine. The short rubber hose and clamp were just long enough and the right size to get a firm grip. It looks really nice with the blue. and is just there to catch and oil blown out.

Got rid of that old clunky air box on my1980 CB900C. These (two of them) were perfect solutions to replacing the engine and trans vents on the deck below the carbs. They also matched the cone vents I put on the carbs. Whole set up looks great. These are an exact fit for the vents (12mm). Only downside might be that the clamps are cheap and probably not stainless steel, but no big problem.

Nice vent. Goes well on valve cover with no issue with the heat. Looks nice. Plastic feel but does the job just fine.

IF YOU HAVE A DYNA HARLEY.....THE MORONS USE JUST A BREATHER 'OPEN' HOSE ON TRANNY/GEARBOX. COMMON SENSE WILL TELL YOU THAT'S A RECIPE FOR DISASTER....I PUT THIS LITTLE FILTER ON AND 'PROBLEM SOLVED'....DON'T TAKE CHANCES WITHOUT USING A FILTER.

An import knockoff of a useful item for large turbo engines.It works though.The hoses are super weak, so get some fuel line and cut it to join to your valve covers and all’s well.

Looks great fit perfectly.

Great and cheap! I needed to make a different air line for my Mexican VW Beetle Bug's Idle Valve and this worked wonderfully to filter it.

I have one on the end of the rear axle breather hose on my truck and another on the air intake of my air compressor. Change out every few years.
