I know, I know... noob question. seen it before, just forgot.
where do I find the deckplates? lowes hardware? I know it's a boat part. not a whole lot of boat stores round here.

 

any marine shop.

 

they're everywheeerrreee

academy sells them.

 

Not to hijack the thread but what's the biggest size deckplate that works with our stock box (3.4L)? I've seen posts with 4", and 6" diameter beckson plates but wasn't 100% positive. Size matters.

 

i've heard of people with a 6". I believe if oyu go above 4", the cutting gets a little harder as you're cutting into certain other parts of the airbox that are thicker or have more support.

 

i have a 4 inch black one for sale. i bought it for 13 from the local store and never installed it. if you have money sitting in your paypal account, send me a pm and well go from there.

 

I went with 5"
That'll be the best size but a little harder to find. The 6" deckplates will look awkward on the airbox. You can still get your airtight seal but the exterior ring will portrude out the side, IIRC.
