bplaney Posted February 14, 2008 Share Posted February 14, 2008 Is this the best plug to get for a change? they are two electrode (and seem to be) platinum. Should I go with Bosch? NGK? Isn't $10/plug a bit much? who has them cheaper than lexuspartsonline.com? thanks! Quote Link to comment Share on other sites More sharing options...
2JayZ Posted February 14, 2008 Share Posted February 14, 2008 Lots of previous discussions on this topic if you use the Search function in the GS forum. Concensus seems to be it's best to go with either NGK or Denso Iridium plugs since they last longest and give excellent performance. Also because changing plugs in the GS3 is a pain in the !Removed! for most of us. Cost should be about $7.50 for the NGK IX and $12.00 for the Denso IK16.

Our cars are very sensitive when it comes to plugs. Quote Link to comment Share on other sites More sharing options...
eatingupblacktop Posted February 15, 2008 Share Posted February 15, 2008 If you were happy with oem and had no problems, why switch? "If it aint broke....don't fix it?" Quote Link to comment Share on other sites More sharing options...

I agree to stick with OE iridiums....either NGK or Denso. The two models you mention above however are not OE plugs & do not have the longevity of the OE ones.

Lexusfreak Posted February 15, 2008 Share Posted February 15, 2008 Again, Only OEM for my lex. Agreed.....the correct OEM for NGK is BKR5EKPB-11 ($8.95 each on sparkplugs.com) & the Denso OEM is PK16TR11 ($7.16 on sparkplugs.com) as you mention.

2JayZ Posted February 16, 2008 Share Posted February 16, 2008 Are you guys (Lexusfreak & dcfish) saying the OEM plugs last longer and give preferred (or better) performance versus the premium class Iridium plugs I mentioned above? The folks at sparkplugs.com list the OEM NGK BKR5EKPB-11 and Denso PK16TR11 plugs as being double ground Platinum center electrode. I thought the Iridium plugs had the longevity edge over Platinum plugs, and were therefore preferred. If you guys say OEM then I would certainly be inclined to agree (especially considering your post counts on the forum) but it seems to go against common sense.

Iridium will last longer than platinum, Do yourself a favor and don't play with fire (plugs) You can mod the hell out of these cars, But keep the plugs original equipment. ;) Quote Link to comment Share on other sites More sharing options...
mburnickas Posted February 16, 2008 Share Posted February 16, 2008 I still have NGK Iridium's and used Denso "I" last time. But I have to agree with Toysrme on this one. You replace them every 60K miles and why spend $8 to $11 per plug when $2 will do the same. Normal NGK are OEM and will work just fine. That is me though...
