Motion Raceworks 4.6 & 5.4 Modular Ford Engine Diaper, NHRA & IHRA Approved (For Motor Mounts, w/Cutouts)

WARNING!!! HAVE YOUR HEADERS Ceramic coated/Jet-hot coated. If you have American Racing Headers then you will need to bend a tube on the driver's side because it's too close. I wrapped my header where it's close to the diaper. I was told that it should work by Motion Raceworks. It didn't work, and burned a hole in the diaper. Although it's flame resistant it will still burn if it's too close. Mine was between 1/4"-1/2" and burned.

Product is well made. It says nhra and ihra approved but no stickers on the product stating that

I put this on a 2006 Mustang with 4.6 3v headers and stock K member. Installation took about an hour due to removing the starter to access the rear header bolt. It fits fairly well and can be installed with the engine in the car. It should help greatly to contain the fluids and chunks should the stock rods and pistons decide to leave the chat.
