I am going to buy some magnacore wires and ngk spark plugs to replace my factory. Is it worth the extra money to get iradium ngk tr55ix or should I just get the tr55's?

 

I don't think you will see any increase in performance with iradium plugs.I run them with my supercharger setup and they work great.It would be hard to justify the cost on a near stock truck unless you are planning on 100,000 mile sparkplug changes.

 

what kind of iridium plugs are you running with the blower? my whipple should be here any day now and i was planning on the tr6's but would rather have iridiums.

 

I'm running TR55IX everything I've seen about these plugs being run on supercharged Ford Lightnings with exceptional results prompted me to try them on supercharged Tahoe.So far I'm very pleased with the results.
