Summit's had tons of returns on the Summit brand boxes.


So true, all of the copy-cats products don`t seem to survive like MSD. I know some have had troubles but there`s a lemon in every product out there. Since I mounted my 6-series box under my dash, I`ve had zero problems.




thats one of the biggest problems for ignition box failures in my opinion, guys mount em in the engine bay. I have mine under the dash, and even isolated by itself there it gets HOT...I can just imagine under the hood
