Default Spark plug

Hey members, I am replacing my spark plugs and wanna get the members point of view. Should I go with Lexus original spark plus at $18 a piece or go for after market top of the line brand? What do your guys think and what brand should I go if after market?

Just my opinion... I plan to go with OEM... !!!

You can find them for around $13-$14 a piece if you shop around..

How do you feel about the coil packs life cycle?

I swapped out the spark plugs about a month ago, purchased OEM from Sewell ($14.67 / plug shipped.) Cheapest I could find from a reputable seller (local Toyota and Lexus dealers wanted $25/plug +)

After changing them out, I did not feel a difference in idle smoothness, full throttle, etc. I suppose that's a good thing though. I doubt the brand of plugs will make a difference, Denso, NGK, etc.
