Bought for my 05 Town and Country which has a 3.8 liter V6 engine. It is very easy to install. Clean mating surfaces and join together. Good durable material. Sealant is not required. I fixed the oil leak I had. Fel-Pro is a great company that makes amazing products. The package arrived sealed and undamaged. Don't buy them from an auto parts store. You pay twice as much as here. Here you can get them for HALF the price. No, it's understandable.
