NGK High Performance Spark Plug

What model, specifically?

Fuel economy will not improve with a change of spark plugs alone. Not unless the previous spark plugs were the wrong height and heat range for the engine.

plan ko sana palitan spark plugs ng exalta grandeur ko. So it does not make any difference compare to the normal one? Mas matagal lang siguro usage nia?

If you will use "high-performance" spark plugs, use NGK platinums that are equivalent in design and heat range to the NGK plugs that already come on your car. And yes, mas matagal yung life niya... which is about the only reason to upgrade.

Depends on why. Pulling the plugs will tell you if they're healthy (slightly reddish tint) or if your engine is running rich. (Black) If it's the latter, then you might need to clean your MAF sensor or check your O2 sensors.
