I asked several times if these were the right parts for my engine. I was assured they were. When the mechanic was to install them. He called and said they were for a 1998 - 2003 5.4 ltr 2 valve motor.

Its a trap! Bought TRQ tie rods and now my front end tires shift from left to right on the road because the parts are cheap and defective from day one. Don't believe their lies with a 4.8 review.

Bought the coil performance coil pacs & plugs for my Chrysler 300 installed them, ran okay but gas mileage took a dive. Milage dropped 10 miles per gallon, took everything out and put my old coils and plugs back in and got my mileage back. As far as performance there was no noticeable change . A waist of money and time, $160.00 to the wind.
