AWESOME
Clay told me about doing this SD swap for my 1997 OBS cover. It's a cleaner look. You'll need to extend the wire pigtail too. And buy the SD tube.

Very nice product
Easy to install and no silicone is amazing

EBP Access Cover Plate
This is a fantastic upgrade from the old, flimsy OEM sheet metal cover. It’s sturdy and well-made, and the stainless hardware adds a nice touch.

Solid
Replaced the hpop and in the process, against my efforts, bent the factory plate. This piece is solid, included gasket is nice, getting the ebp tube back on is still a pain but likely bent that a little too.

Will recommend this to friends

Beautiful Piece
Plenty of options for HPOP gear covers out there but these really shine. Lots of thought was put into the design; the O-ring seal has worked flawless for about a year still no leaks. Plus no more bending sheet metal when removing the EBP sensor.

Great part
Make sure to apply anti seize to the threads. On my second one due to me.

Best cover out there
This fixed my issues with the weak oem cover plate. Install was much easier with this Riff raff product.
