    Exact replacement, the hardest part was removing the intake manifold, just takes a few minutes if you loosen the braces. Plugs went in easy, then realign the manifold and make all of the connections.

            These are factory replacement on the newer Dodge 3.5L LX series engines. Plan about 1-2 hours as you have to remove about 25 nuts and bolts to take off the upper manifold. Original plugs needed replacement at 115,000 mile so this won't have to be done again. Engine runs smooth.

              These are OE in the 300M Special, and I have not found a better plug for these motors. They help the car idle smooth and run great.

                Chyr tells me to use only these on my 2008 Pacific. Other plugs can cause electrical problems down the road. These are OE plugs.
