I currently have 98 coils on my turbo build engine, but in my garage i have a complete 02 5.3 swap with the square coils with exposed heat sinks. I couldnt find confirmation via search if these are the coils of choice for forced induction. Also, someone said that the plugs were different on the square truck coils Vs, the F-body coils. Well, since i have both pairs of coil wiring harnesses, i would just use the complete coil harness off the 02 5.3 truck coils on my turbo ls1 combo, correct? Which is using a modified 98 wiring harness. thanks

 

The coil model number is D585 ignition coil, those have the heatsinks on them.

you will also need 2 wiring harnesses 12601824, and possibly two coil brackets, unless you relocated them 10457736

 

thanks! Soo since i have the complete 02 truck coils and matching wiring harnesses for them already, i could just swap em out with the 98 coils/wiring on my current turbo setup?
