Does this do both sides or just one?
Alliant Power Stand Pipe & Front Port Plug Seal Kit for Ford (2003-07) 6.0L Power Stroke
I am doing injectors on my 06 power stroke. I believe i have the updated plug and stand pipe. They use a 12mm Alan to remove them. I want to order new seals can you clarify if i need 2 kits or one kit. Thank you
