you can find it for cheaper at jegs. i got mine from summit cause most places its back ordered.

i literally got one of the last NEW m1's available on the market. theyre even back ordered through the dealer. so if you want one get one quick before theyre gone.

i paid just under 500 for mine though summit after the price matched jegs price.

Switching to an M1 is no more difficult than doing the plenum. Actually, it's easier..... don't have to deal with the plenum at all, just a direct intake swap. if you have the cash, do it up, you won't regret it.
