Beckson 4" Smooth Center Screw-Out Deck Plate - Black

Used to create an access vent for the ac in my cummins. Leaves and things get in there and stuff up the system, let's you get them out easily with a clean looking install. The o ring made sure my ac didn't come out in places other than the vents. Easy to open and close.

Use this deckplace to make a direct intake into the airbox (before the filter) of my off-road Toyota 4Runner. Gives the air a direct inflow to the filter. Works great and easy to install. I can screw the cap back on any time I need to protect the air intake at a water crossing or extra dusty conditions. See "Deckplate Mod" on the T4R forum. M

Used it for a heater box clean out in my first gen Cummins. Worked great.

I love it works perfectly.

Worked perfect for my project
