Dress up your engine bay with our new billet coolant reservoir cap. This billet cap fits over your existing coolant reservoir cap to give your engine bay that extra shine. The cap will be a very snug fit so you can still use the cap per normal and not have to worry about it slipping off. Available in 3 different sticker styles or without a sticker so you can add your own personal touch. 

COLOR NOTE: The two available cap options are our black classic ZZP logo and the new ZZP flag logo which features red accents. Both decals are chrome base.  Also available with no sticker. 

Fits: 2016-2021 Chevy Camaro, 2013-2019 Cadillac ATS (2.0, 3.6, and V models), 2012-2020 Chevy Sonic, and many more. This cap is intended for (and should fit all models with) GM coolant reservoirs that use the newer 20psi cap, not the old 15psi style.
