was going to change the plugs on the wife's 2002 RX300 and bought new ones at autozone. I got the bosch platinum ones. Got home and under the hood is a little sticker that says use iridium plugs. what gives?


can i sue these plugs or should I stick with iridium? NGK or what?

thank you,

Sully

 

I just did my plugs today. I bought the NGK Platinums @ Autozone for $2.99 a piece. Napa has them for $2.49 but they were closed today. Maybe they price match?

 

I would stick to exactly what your manual says. They are NGK's. They are $9.02each at Advance Auto Parts... Don't venture away from the original plugs.

 

I agree. I am the same way with my 540i. The platinums I purchased were allegidly OEM approved by Lexus. I been laid off for a while now and could not afford the NGKs you are referring to so I had to opt for the NGK platinums. We could not afford a tank and a half a week in gas.

 

Iridium recommended. But i am using "Pulstar BE-1 Pulse Plug" since october 2009. No problems great performance.

 

I am voting for the IRIDIUM, either Denso or NGK. Both are the finest plugs I've ever seen. I can't even fathom any other plug lasting as long as they do. I purchased the new plugs (same as original) BEFORE I removed the old ones. At 97K mi. they looked almost like new and checked the gap, it was exactly as new. I wouldn't dream of using anything else. The car has 150k + mi. on it now and if I had checked the original before I bought the new, they would still be running in it. I would throw the BOTCHED (Bosch) plugs in the trash can!

BTW, I bought the original Iridium plugs for about $8. ea on E-bay.

 

X2, stick with Denso or NGK.

 

I'd go with the iridiums, too, if for no other reason than they last longer than platinums (and they are a b_tch to change).

 

Are the above iridiums suggested for the ES 330 as well?

 

look under your hood, mine said use iridium only....Hey they last an easy 125k miles, best plug for the value....Bosch are really sucky plugs....
