For true power hounds, programming the perfect tune is a necessary step on the road to customization glory. It's more than just plugging in a chip—it's years at the track testing torque output, recalibrating tire sizes and mastering your fuel mixtures. Problem is, taking your ride to the mechanic is like playing a game of digital Russian roulette—one false move and your tune is toast. So, block unwanted access to your diagnostic port and keep your car custom with the DiabloSport OBD-II Port Cover.

Precision cut to snugly cap your OBDII port and boldly stamped with the words “DO NOT REPROGRAM," the DiabloSport OBD Port Cover clearly identifies your ECU as a no-go zone. And, the legendary DiabloSport logo in the center tells the world your ride is equipped with pavement-searing power. Plus, the DiabloSport OBD II port cover is carved from premium billet aluminum with an aggressive anodized red finish. So, you get serious interior style that never rusts. Even better, DiabloSport backs your OBD Cover with a 2-year warranty.

This cover is excellent quality, I am very impressed with it. It Keeps the Ford dealer from "re-programming to default" my set performance parameters on routine maintenance visits. Or at least it puts them on notice when they see their code reading machine will not plug in.... Then then the mechanic will check the work-order that they failed to read in the first place, and see I TOLD THEM TO NOT TOUCH MY PORT!this will change my parameters.They leave it alone and all is well with the world. :)

looks fantastic
