Best ones would be IK22. Use IK20 for stock. Should be able to find them on US ebay

denso iridium power,ive used ,

how much dave, and where did you get them from?

IK20 and IK22 are Denso Iridium power. Get them from ebay unless you want to price x3 the price in the UK. Should be able to get them for about £40 for 6.

i paid top wack andy,about 60 quid,next day deliv from sparkplugs.com i think,have the reciept somewhere,they are a lot cheaper on ebay places but i havnt a credit card to buy stuff .hope this helps pal.think aido got some from ebay he`ll help you out .

I bought mine from someone called dohccivicna1250 but it looks like they pretty much just do alloy wheels now.

nice 1 mate

Be carefull with buyig them from the U.S, even though they label the package as a gift, customs still sometimes sting you with the tax.

I use NGK Laser Iridium IFR6T11

No problem at all. But they charged tax (11 Euros in Gemany) for carparts. Bought a set of 12 IK20 from this guy: LINK

Just look forward in a LOC-Groupbuy.

Never mind. Will never use NGK again. I had to change them because one plug looked like this: LINK.plug#6

after 90.000km (NGK IFR6A11)

I got the Denso Iridium IK20's from AutoPartsWarehouse2000 on ebay. Cost me approx £37 including postage. They come pre-gapped so it was just a matter of 'plug and play'.

Shipped from the States in 3 days with no additional customs tax to pay.

also have a stock engine with....wait for it.............



Yes, Denso Iridium power IK20's as well.....

Bought 6 on US ebay for around 30 something quid plus small fee for postage.

I love the pound being so strong against the dollar for us ebay parts

ebay name

sparkplugssource

Plugs went after 'NINETY THOUSAND KILOMETRES!!!!???'
Is that right? I'd change once per year myself!!
Keep it sharp!

They are meant to be changed at 100,000Km! Some plugs are good for 100,000 miles. Labour charges involved in changing the plugs on some engines cost more than the plugs so you wouldn't want to be doing it every year.

right I'm gonna buy some denso iridium sparks plugs iK20's. I've seen them on ebay for about $45, they are £69 from sparkplugs.co.uk. Just wondering If any one has bought any recently from ebay in the US and could recomend a particular company or person that is selling them and what price they eventually paid all in.
Cheers

also how long did it take as I ideally need them for thursday
cheers

i got some from a guy called "performance parts store" they were very quick and helpful, postage took about 3 days and was $15 ( actual cost of postage was about $18)

i asked them to put NCV ( no com' value) on the label, it took a few requests but they did it in the end.

Mine came from dohccivicna1250 who was fine, took about a week for delivery, think you're asking a bit much to get them over from the US before Thursday unless you pay through the nose for express shipping via one of the big couriers to be honest mate.

If you can wait the extra time get them from the USA, the other option you would have is the HKS plugs that Dave is selling if he has those in stock?

got 6 left...........
