When I go into boost my spark plug wire connection to the distributer keeps coming off. Only happens under boost. Is this something thats normal or is it a sign of a problem? Engine is a 9:1 81.5mm b-16 @ 15lbs of boost.

 

zip tie them, some do that, i know my msd wires did it

 

Yes, they are MSD wires. Anybody else having this problem with MSD wires?

 

yea, just switched to ngks. i just looked at the one that kept coming off and spread the metal inside the boot apart and it didnt come off so u could try that

 

easiest way to fix, is zip tie if u dont wanna by another set, but if u dont mind, just get a set up NGK blues

 

Imma try zip tying it. I tried bending the tabs once but that held for only 1-2 pulls.

 

mine do that ima crimp them a lil tighter

 

black zipties ftw

 

i thought i lost a cylinder at the last track day....my GSR sounded like a Subie and had no power. I had the same problem as you...the wire fell of the plug on the distributor

 

msd makes newer style caps with a plasic piece that screws on to hold the boots on the terminals. maybe one of these is in your best intrest.
