I was missing some vacuum port plugs for my Holley carb. Kit included all replacements. Good quality rubber. No problems and solved my vacuum leak issue.

Used the 1/4” short to plug the air intake breather connector on 2008 Trailblazer. The LS model doesn’t have a breather tube just a nipple plug. Looked on GM parts websites and auto parts stores with no luck. The 1/4” is a perfect nipple plug. 10 second install now idles lower and quiter, likely better power and mpg.

I have used these caps since I bought my first car in 1980.They still work, they are still cheap, but the quality is not the same as they used to be.These will work for 2 maybe 3 years, then need to be replaced. They dry, crack and cause a vacuum leak within that few year span. They used to last as long as the vehicle.

Buying an assortment makes more sense than buying one size, it you can. I have only needed one cap so far. As I clean under the hood I will probably use more.

Work good but wouldn’t recommend for automotive applications because the heat cycles will make them crack

needed only one piece and worked as a charm; worked as needed - to stop leakage on the power steering reservoir during flushing. does not need the rest but who knows that i might need it sometime somewhere.
