Customer Reviews

Floor & Tunnel Shield II

Great for bus conversions!

"I contacted DEI's customer service and asked what would be the best product to use, and this was recommended. They were a great help and this product was easy to work with. The engine cover is awkwardly shaped, but the tunnel shield was easy to cut and mold to how I needed it. If I need anymore products, this will be the first place I go to!"

GEN-3 Onyx Turbo Shield

Great Quality

"Ludicrous speed shipping; somehow they got both my orders to me on the same day, in Japan, in less than a week from the time they shipped the items. Their customer service team is wonderful to work with as well. I've always trusted DEI and will continue to do so."

Black Titanium™ Exhaust Wrap Kit

Worth the Money

"This kit is great - I was able to use it to wrap my 1973 Jeep CJ5 headers. I had been having issues with heat on my alternator and wires. This kit solved all that, and looks pretty badass under the hood. I have several friends that have used the same kit for their jeeps since seeing mine."
