We designed the Snow spacer to use an O-ring to seal on the mating surfaces so you never have to worry about a boost leak or getting that silicone junk all over the place. (Show B-roll of O-ring installed on the plate) If you want even more power gains and greater safety, we have you covered. Snow Lid Spacers feature 1/8 NPT ports above the runners, allowing you to simply remove the plugs and bolt on a Snow Performance Direct Port Water/Methanol system. This provides you with an equal distribution of water/methanol across all cylinders for those looking to maximize performance and reliability! (Show bolt-on direct port plumbing for the manifold, and then show a plate with the direct port bolted on). It's worth noting that you could alternatively install a NX shark nozzle direct port nitrous system in our spacer as well. Ready to add easy horsepower to your LSA Supercharged vehicle? It doesn't get any easier than the Snow Performance Billet Lid Spacer.
