Default Recomended Spark Plug

I am changing the plugs on my '10 LX and trying to see what are the best type for the engine. I only use synthetic oil, looking for the best gas mileage. Or performance, whichever are best for my car!

Whenever I change plugs on Rios, I use NGKs, part# 2382. They are just a standard resistor plug, which is what all those Rios came with from the factory. I believe they cost around $2 each, maybe even less.

There are platinum and iridium plugs available, but you could change the standard plugs multiple times for the same price. Platinum and iridium plugs will last longer, and possibly provide a very slight performance increase(noticeable???), but cost more. If you decide to go with these, I'd go with NGKs, or Densos if available. I'd stay away from Autolites, as I have seen them break off ground electrodes and cause engine damage.

Standard plugs unless you have upgraded you ignition, or grounding system, along with better wires....


Sorry. They really market to us so much. Our electrical systems are not meant for these Platinum 4's or what ever kick butt $6 - $8 plug they are selling right now.

Use regular copper plugs, your choice as to brand. Use a loop for gapping, not that disk thing, and you really shouldn't have to worry about them for 60 to 100 thousand miles.

Well... That's my two cents. Hope it helps.

Not sure where you're coming from with this idea. The ignition system just makes a spark and this has nothing to do with the type of electrode. Electrode type influences longevity more than anything else. It's usually only the centre electrode that is made of exotic metal. Heat rating of the plug is determined by insulator length and design the of centre terminal. Correct installation is also important.

OK Cuda,
You get a +1 for that.

Here are the brass tacks though. Do you have a high performance engine? High compression? Low compression with boost? Aftermarket ignition system? Do you have to run a different gap on your plugs? This is what you would need a smaller filament, or iridium for.

(PS they do have to put a resister in plat, gold and silver plugs because of the skinny filament)

You will also not notice a gain in HP or MPG unless your current plugs are just horrible. I would go with the NKG's so +1 for the 2382's.

Easiest way for quick and easy MPG and MPG are Cold Air Intake, and Freer Exhaust.
