The exact part number slips my mind., I'll have a look tonight when i get home, but when I got mine back in Januaray the best place to get them is eBay USA, even with the shipping they were still considerably cheaper than any price I could find find in the UK.

i got mine from here(USA) with postage and import duties (if they catch you) it'll still be cheaper.

i got all my service parts from there and when i got my plugs it worked out at 80p each!!! and yes they are the correct platinum ones.

Thanks for the info guys. Rockauto look good on prices......however

I need to know the correct plugs for my 98 LS so I can order the right ones (they have a few to choose from!)?

if you start from the rockauto home page you put all your car info in and it brings up a chioce of about 20 plugs for your car. you need iridium(something like that!) or platinum. i went for the bosch ones which were $1.66 at the time(£2.67 now!) and they are fine. it still works out half price if you go for the denso ones but then with p+p and import its not a great saving.

depends if you want to save cash and aren't fussy about original replacement parts.

$66 for denso delivered which is about £35. plus a bit of import duty.

still a good price

it's possible to get around the import duty by asking the supplier to mark the parcel as 'a gift' and declaring the value at under $50

[MAT_8N]

i know, but when i ordered i ordered all my service parts and some brake pads so it went over $50.

i got stung for import duties but it was still loads cheaper than uk prices and it only took 48 hours to get here!!

Excuse me for asking somthing which might be obvious to everyone but, I thought that Lexus now used iridium tipped spark plugs. Also, what is the difference between platinum tipped and iridium tipped spark plugs?

Sorry if this is a daft question.

[MAT_8N]

not sure exactly but i think its life span? i think iridium will do 60k miles where platinum are only good for 40k miles?

i only do 5-6k miles a year so i'll be changing my plugs again before i do another 60k!!

Nice one. That explains why every 60,000 or 6 years, you get a big bill from Lexus.

Hence the reason I'm trying to find out what the correct plugs are

[GoldfingerLS]

For the 98+ MkIV LS400 with VVTi the OEM plugs are Denso iridium SK20R11

They ship with US Postal and you have an online tracking on where the parcel is right now.

I got 8 off SK20R11 from eBay for £25.00.

its worth keeping an eye out for them, but none on eBay at present.
