Yes they are the plugs is that from Us. Lexus birmingham do them for circa £80.00 i believe.

Also found these cheaper still.

I git these from driven2autmotive for £40. Someone said on a different forum that these plugs are slightly longer than normal ones. Is this right.

Surely you need FK20HBR11 - these don't look like that to me.

The FK20HBR11 is standard plug, the people from the place I got these days the IKBH20TT is a better plug than the original one. The OEM part number for IKBH20TT is 9091901249 which is the same OEM as the original one.

Oh - seems they're OK - a lot cheaper than FK20HBR11 - but FK20HBR11 is listed in the Denso catalogue.

Sparkplugs. co. uk list these as alternative / equivalent.

It looks as if these IKBH20TT are newer, so may be better. Some kind of strange pricing anomaly going on.

Even cheaper here:

£6.72!

I know very strange. What do you drive?

All very odd. 

Green Spark plug company are suggesting that they are different sizes, whereas Sparkplugs.co.uk say they are the same.

The part number 90919-01249 is for the FK20HBR11 though and the newer spark plug is showing up as an alternative when cross-referencing.

Personally, I'd probably stick with the normal spark plugs - after all, they only need changing every 60k miles

[kellogsj]

When it says different size, does that mean the thread or the length of the plug.

Well, see here:

http://www.denso-am.co.uk/media/698507/2015denso457-irtt-product-update-.pdf

These came in November 2015, so presumably more or less replace FK20HBR11 which date from pre-2005.

They are specified for more Toyota models (mainly Japanese market) so that might explain the price (vast) reduction.

And if, as implied above, Lexus Birmingham are supplying these when you order FK20HBR11 - they're making quite a mark-up!

Thanks for your help. Hopefully then the ones I have should be good to use. I'm also replacing gaskets when the plugs are being done.

The only things that matter are the thread diameter (14mm) and thread length (26.5mm) - same for both.

The Denso catalogue here: http://www.denso-am.co.uk/e-catalogue

lists both types, IKBH20TT under 'TT' and they're promoting TT as the latest and best.

Thanks for bringing this to our attention - my plugs are due for a change really and these prices are a lot more reasonable than I was expecting!
