Coupon Exclusions

Parleys Diesel Performance is dedicated to offering you the best pricing all the time. Our sale coupon allows you to receive the absolute rock-bottom price for each diesel performance product we offer.

The coupon does not apply to certain brands because those products are already listed at the very lowest sale price their manufacturer allows. You won’t find it anywhere cheaper!

The following brands are not part of this sale coupon:

• AEM

• AIRDOG

• AIRAID

• ARP

• BANKS ENGINEERING

• BD DIESEL

Again, entering the coupon code on products made by these manufacturers will not result in any further discount from the listed sale price. These products are not part of the coupon because they are already listed at the absolute lowest price that the manufacturer allows.
