I bought some Accel 9059C cables a while back and took the opportunity to put in some iridium plugs while I was at it. Little did I know how difficult replacing the passenger side plugs and cables would be! I got the driver side done really quickly and then went over to the passenger side and about choked! It's crazy how much crap is obstructing the way to get to the plugs. This'll have to wait until the weekend.

Here is a reference clip that I found of someone explaining what they had to do to get access. What a PITA!

Did you at least use the correct plugs?

As designed by GM, the 1975-80 model year Buick Skyhawk, Chevy Monza, Pontiac Sunbird, and Olds Starfire that were equipped with the 3.8 liter V-6 required disconnecting the motor mounts, attaching a chain hoist and lifting the engine a few inches in order to be able to access and replace the right bank plugs.

Which are the correct plugs that you’re alluding to? I figure that you may be referring to TR6IX/TR7IX based on your previous posts.

LT4 uses a longer reach plug iirc 25mm

TR6/7s are 18mm reach are for LS

LTR6/7IX should be the correct plug, NGK 6510s gapped down to about .030

I have the LTR6 plugs and am thankful researching these forums landed me on the right plugs. thank you guys!

Just curious, why did you replace the plugs?

I bought the spark plugs to go with some Accel 9059C cables that I ran across while browsing for upgrade parts. The cables were priced $50 less than just about everyone else you could think of who sell them for $150 and I also got free shipping too so I just said screw it and decided to buy the cables. While I don't need them where I am at with mods right now, maybe they'll be of benefit later when I start working toward 700whp over the next couple of years. If anyone is interested doing the same thing you can get the cables here (link).
