Default Spark Plug Preference

I have been running NGK Iridium Plugs in my vehicles for a few years now and now I am making the switch over to pulstars. I swapped over to them in my camry and I am trying to justify spending $12 a plug from O'Reilly. Yeah there were only 4 and I also gutted my cat on the car with a home made spacer on the secondary O2 sensor to trick the ecu into thinking the cat is still there. The reason I gutted the cat on a 4 banger Camry wasn't for the hp or tq I MAY get but it was b/c the cat was blocked up due to the use of seafoaming the motor. Back to topic I got lower RPMs at highway speeds. More tq through out the RPM range and best of all more MPGs. Now I am wondering if anyone has swapped to them in their Nox and got more MPGs. I am determined to get 19-20 city and I am gonna do everything in my power to do it. So what plugs are you all running?

I liked them better than other brands. Especially in iridium. I think stock in the nox already are iridium plugs so swapping to the pulstars won't be as noticeable difference than going from copper to iridium

Yes iridium on the NOX. But I'm not sure it is NGK, I think it is the iridium version of Ac Delco.

This maintenance is coming on my truck, the three behind the engine will bu a pain in the ass

Try swapping the plugs in an 01 Accord V6 when it has a blower...needless to say you have to pull the blower b/c the drive shaft runs right over the front 3 coils lol. i'll post pics of the old car tomorrow.

yes this is what i will do soon. will change the plugs and wires. i figured out that best way is to remove the ignition coil and then you will have space for hand to pass.
