I think they only have 9 degree plates and light springs.
I just use little washers to limit travel under the slot at the stem. I vary the thickness depending on how much travel I want to take out. .012"...
I use the red tops without any issue or discharge problems. I maintain good grounds on all electrical parts. i'd use another in a heartbeat.
locked out distributors can break starters. if you have an MSD use a start retard.
I went thru a low rpm mis-fire in my r/t. might have been the harness but I couldn't for sure pin it down. stripped the electronics out and went...

there isn't anything equivalent to a j11y in my opinion. an autolite ap85 is close and with a platinum tip.
i have a box of mopar plugs marked 34p which are actually j10y's. the j10y was the performance plug for street wedges until the j11y which I...
what's interesting is to compare the projected tip length on the j11y to a j10y, j12y, autolite 85, 74, 75 or any other 14mm 3/8" reach plug....
