NGK 5464 Iridium IX vs NGK 4996 Laser Iridium Spark Plugs

[Cigar_Maverick]

Buying new plugs for my 2007 Yaris. I've had it a week and it currently has 106,000 miles on it. RockAuto has the NGK 5464 Iridium IX for $5.93 & the NGK 4996 Laser Iridium for $6.07. At that price I was just wondering the difference? Preference?

Thanks,
Russ

Any plug will last 100k now so it's moot.

Hmmm. OK. Then I guess I'll just pend the 14 cents more for the better ones if everything else is equal. Thanks for the help! :biggrin:

My wife's Camry has 130k on the plugs and it's running like it did 12 years ago.

100k change interval.

i have the ix plugs when i got my Vitz RS counter parts from japan, ecu tuning, header etc. purpose of the plugs are to handle more heat/heat range...if you abusing your car like me or turboed, go for higher range plugs like ix or laser 😀

interesting, if you go to the ngk web site it shows the 4996 as OEM and the 5464 as on option

same heat range,same gap, same resistance, but the 4996 has a 8mm center electrode for longer life, where the ground electrode of the 5464 is tapered for "faster starts and better acceleration". !!?? I blew up the pic and the ground is tapered,sure as heck. So if I take a dremel to the ground on the 4996 do I get a faster,longer life plug?
