Enhance Your LS Engine’s Cooling with A Four Corner Steam Line Upgrade
The LS engine has some unique cooling system features that can make an LS swap a bit of a head scratching affair. One of these issues is the OEM LS steam vent system. Most LS truck applications only run a steam line to the forward end of the cylinder heads, and this line often runs through the throttle body as well. Performance LS variants will run a four-corner steam line kit from the front and rear of the cylinder heads, but the OEM LS steam vent tubing is nothing particularly impressive to look at if you’re building a super clean LS for your ride. The best solution is to ditch the two-port truck setup or the OEM four-corner LS steam vent system for a custom bent LS 4 corner steam vent kit with AN hard lines and manifold system. This LS steam vent kit setup has proven to be more effective, and most certainly is more visually appealing when you’re putting a lot of time, effort, and budget into making your LS look as good as it performs.
Aluminum and Stainless Construction for Long Life and Leak Free Fitment
Upgrading your LS engine with a LS 4 corner steam vent kit shouldn’t take hours of cutting and bending hard line and trial and error fitment. We’ve done all the hard work for you, creating a precision fit LS 4 corner steam vent kit that bolts right on with basic hand tools. Our hand built 304 stainless steel hard lines are cut and bent for a perfect fit and include black anodized AN 4 tube nuts and ferrules installed over pre-flared ends. A black anodized aluminum distribution block, black anodized O-ring sealed port fittings, and black zinc plated 90-degree AN to NPT adapters fill out the rest of the kit. Stainless steel Allen hardware and Teflon tape are included for assembly and installation needs.
Designed To Fit Most LS Engines and Popular Aftermarket Intake Manifolds
Our stainless-steel and aluminum LS steam vent kit is designed to clear popular long runner and mid-rise aftermarket intake manifolds, including such popular LS intakes like the Holley Hi-Ram, Holley Sniper, FiTech, Edelbrock Victor Jr. and Super Victor, BTR Trinity, and others that provide at least 1.50-inches of clearance between the LS valley cover plate and the bottom of the intake manifold. We designed our LS steam vent routing to clear OEM Gen 3 knock sensor locations, but this kit will not clear OEM low profile plastic intake manifolds such as the LS1, LS2, LS3, and others. LS engine applications include all 4.8, 5.3, 5.7, and 6.0 Gen 3 engines and 4.8, 5.3, 6.0, 6.2, and 7.0 Gen 4 engines. Note that LS3, L92 and similar cylinder heads with front steam ports only will require the removal of the rear steam port plugs for installation of this four-corner hard line kit. Upgrade your Gen 3 or Gen 4 LS engine build today with our great looking AN hard line-based LS 4 corner steam vent kit.
