Does anyone by any chance know the right depth of the spark plugs... i have a 2003 mustang gt with a 8lb blower.. and my buddy gave me a pair of Zex spark plus +4 made for blowers and nitrous... but compaired to the old spark plus i have it seems like the plugs would go deeper into the cylinder. just curious if anyone might have any info..

I'd toss the "Zex" plugs and stick with known quantities for a blown mod: NGK TR6 gapped at ~0.035"

I'm pretty sure I read that regardless of the thread length, they'll bottom out where they need to sit.
