DaystarKU71124RE Red OBDII Port "Do Not Flash" Plug

This 'Do Not Flash' cover works great and will do the trick to save from a costly vehicle error. Only one problem and hence the three stars....It is simply overpriced for such a tiny bit of plastic!

Perfect to prevent dealerships or shops from accidentally changing my car’s custom tune and harming the engine

Fits well and is not loose like some said. Definitely pricey for what it is, but hopefully is worth it.

Cheap plastic, wouldn't recommend

Need a dust plug but I also use a SCT flash tuner2009 Ford RangerIt fits great

Fits well and looks great

Looks cool but it is really a thin lightweight plastic cover but it does protect the connector and warns not to re-flash.

Black lettering coming off after a month.

Worked as intended but way too expensive for a small piece of plastic. Unfortunately I didn’t have much time to look around as the truck was heading into the dealer and don’t have a lot of trust in them.

Expensive for what it is. I went for the red version as it should stand out better to techs at the dealer. Fits fine - not too tight and not too loose.

Received as I expected! Good product shipping a little pricy though.

Didn't fit on a 2014 Mustang
