Central Coast Mustang makes P specific long and short tubes, and
www.fordracing.com (ford itself) also makes P specific shorties. You can get discounts on Ford stuff at www.oemfordparts.com.

My BBK unequal shorties fit well on the passenger side, but on the drivers side its a different story. The #7 sparkplug is very close to the header, and I had to use a 90degree boot end on the wire for it to work. I'm not sure if i'm gonna be able to remove that plug without taking the header loose or not. thats gonna be a major pain in the ***. It looks as though a short plug for #7 would make everything fine, but I can't say for sure yet.

I've heard the MAC 1-5/8 longtubes fit well, but haven't seen any in person yet. As soon as I do, and if I like the fitment, I will buy a pair.

For you, I would suggest finding a set of P specific shorties and not worrying about plug clearance.

good luck,
