[shafque]

Hi there

I have been told that i need to replce my spark plugs. but i don know know which one. Do i have to used iridum plugs? My car is a (1999) T - Reg IS200.

There is so many different types of plugs.

I have found these on eBay.

They are cheap then the rest of them.

Can anyone recomend this set.

Please advise.

Ive never tried them,but some guys on here have said the is200 can be sensitive to different plugs ,so id buy the denso plugs to be safe.However ,wait and see on the forum for help from others first ,as they may have more info about these.

Don't know how many times I've posted this now! Lol!!

IS200 is sensitive to plugs and you must use the correct ones. That is Denso or NGK irridium. Denso SK20R11's are OEM. You should be paying about £60-70 for a set of 6. Try and buy cheap plugs and you'll regret it...

[shafque]

ok

these are irdium and made by NGK.

What do you think of this chris?

[ChrisIS200SportTTE]

Yeah they seem to be the right ones. I just can't work out why they are so cheap? :)

These are what I have in mine. They are Denso OEM and are what Lexus would have put in your car at the factory

If it were my money and my car I'd buy these for an extra 20 odd quid :)

[shafque]

ok many thanks.

[Mr.Rudus]

iridium all the time.

denso

sk20 or IK20.

its simple -

[shafque]

Mr Rudus which is the bettre plug SK20 or ik20 ?

[ChrisIS200SportTTE]

SK20's should last up to 60-100,000 miles.

IK20,s last 20-30,000 miles.

IK20's are a 'performance plug'

only really beneficial if your running boost, i.e. supercharger or turbo.

[Mr.Rudus]

i prefer the IK20's, marginally better.

better acceleration by less effort, mpg and smoother throttle response.

not a big difference though.

less life approx. 40-60k whereas the SK20's approx. 100-120k

tried & tested!

[ChrisIS200SportTTE]

Although in the service schedule Lexus say to replace SK20's every 60k. Not sure I'd run any plug up to 120k but yes I've read they are meant to last that long.
