LS family of engines -4AN anodized BLACK aluminum Steam Vents with hose & hardware for front and rear venting. Complete kit.Designed specifically for 102 or 92 manifolds.This driver front and passenger rear vent ports cause the most fitment issues; this raises issues with installation. Which may result in being required to lift the manifold. We have installed the kit in the shop without the need of lifting the manifold. However it takes patience and a bit of luck. It is possible you might need to lift the manifold approximately .5" to clear these two corners. Once you get the AN fittings threaded on the steam vents on the two corners the rest of the kit is a simple install.

2) stretch the hose overnight and apply some heat
3) buy the -4 to -6 hose adapter hose with fittings located item
Installing steam vent reliefs on in all four corners of the engine have been proven to limited detonation in chambers 8 and 7 specifically. A must for high horsepower engines!!!This is a high quality kit that will flow well and be a great improvement over stock steam vent plumbing.
