Check the listing for details. LS1SVBN Steam Vent Kit -4 AN / Complete LS1 LS6 LS2 LM7 Coolant Crossover BLACK. Condition: New. Listed at 149.91 USD. These are the highest quality fittings available. Many people on eBay have copied my kits and even screenshot my kits on my engines which I used to make the kits. These are not cheap Chinese kits. I recently had a shop call me complaining on my kit leaking… turns out the shop owner told his customer to buy my kit, but buyer thought he’d save a few bucks because it looked like same kit on same engine… kit that was cheaper (from a California seller) it was crap. Your spending thousands on your project, saving a few bucks will cost you more later. No shortcuts. Don’t be fooled. Note... you will not find a nicer set anywhere... on ebay, or any major name brand supplier. Just a fact, not an advertisement. :-) LS family of engines -4AN anodized BLACK aluminum Steam Vents with hose & hardware for front and rear venting. Complete kit. Won't fit FAST102 manifolds, sorry.

See my other auctions for other styles and colors. Note: Some cars may have larger 3/8 barb fittings on their radiators. If so there is one of a few solutions. 1) try like heck to slip the -4 hose over the larger barb with some WD-40 2) stretch the hose overnight and apply some heat 3) buy the -4 to -6 hose adapter hose with fittings located item #141990963697 ...
