GTI Spark Plugs

[xxx_mojo_xxx]

Are these the correct OEM spark plugs for MY08 GTI?






Thanks

I would also like a definitive answer on this as I'm looking to have mine replaced on my 06 GTI in an attempt to cure a misfire/hesitation problem.

I thought the correct type where 06h 906 611 but I have been given 101 905 631 H ????

101905631H  is the right one for the cupra tfsi

Is the Cupra tfsi the eqivilent of my GTI (ie not an ED30)

OK - the definative answer.

For standard GTIs & Ed30s, the correct plug is 101 905 631 B - which corresponds to a Bosch F6KPP332S.

For higher power 2.0 TFSIs as used in the S3 and LCR, the correct plug is 101 905 631 H - which corresponds to a Bosch F5KPP332SBB.  This pug is also backwards compatible to lower powered variants, including the BWA 200bhp version, and is probably the best bet for any tuned motor.

UPDATE:  That part number is now superceeded.  The new part number is 06H 905 611.  The 'spec' of the plug is identical - but VAG have just removed all Bosch references - presumably VAG are trying to make it difficult to cross-reference with Bosch 'retail' spark plugs! 

For higher power 2.0 TFSIs as used in the S3 and LCR, the correct plug is 101 905 631 H - which corresponds to a Bosch F5KPP332SBB. 

EDIT: I was sort of right.  The H plug is ONLY for 265PS variants with the uprated high temperature pistons.  The Cupra and Ed30 have standard pistons, and need the same plug as the standard GTI.

This pug is also backwards compatible to lower powered variants, including the BWA 200bhp version, and is probably the best bet for any tuned motor.

I was talking tosh there!    If you use these plugs in a non S3 or Rocco R donkey - you risk burning a hole in your pistons

£9.63 each + vat - not yet in the TPS parts club.

Stick with genuine OEM Bosch plugs.  Volkswagen spent 1,000s of Euros determining the correct plug - and I always recommend sticking with what the manufacturer knows, rather than some pizza-faced dork at your local Halfrauds or A1.  Incorrect plugs can cause serious damage - like literally burning a hole through the top of your piston.

My dealer quoted my 06H 905 611 (Bosch) or 06H 601 A (NGK)  for my Edition 30, I went to SERE motors on SCN who said neither of those P/Ns were the same as the those quoted fotr the Leon Cupra 240 but were the same for the LCR - 265.

My dealer quoted my 06H 905 611 (Bosch) or 06H 905 601 A (NGK)  for my Edition 30,

(edited NGK part number)  Yes, these are identical to the 'new' part numbers for the standard 200PS GTI.  Factory fitment was Bosch, and NGK are now listed as an alternative.  But the Bosch are a higher spec plug.  They do a similar thing for the FSI V8 (as used in the B7 RS4, R8 and A6 allroad) - the NGK can be used in all three (the two high power V8 variants in the R8 & RS4, and the low power A6 allroad), but the Bosch can ONLY be used in high power variants.

I went to SERE motors on SCN who said neither of those P/Ns were the same as the those quoted fotr the Leon Cupra 240 but were the same for the LCR - 265.

I think they may be using an old ETKA.  The 200PS/230PS/240PS all share spark plugs with an identical heat range.  But the high power 265PS versions used in the S3, Rocco R and LCR, which all have considerably uprated pistons, make use of a hotter spark plug - currently the H variant shown in the first post.

If you use the 200-240PS plug in the S3/LCR/Rocco R - then you'll get a misfire - especially when cold.

i just changed mine tonight even thought there were only 3k old, i had the bosch ones on the very first pics, now I've got the Ngk ones part no. 06h 905 601 A.

only went round the corner to see if it fixed my problem im having and so far it did but it was only round the corner lol, my plugs that were 3k old were black is this usual?

If you are changing them every 3k miles - then budget for a new cylinder head.  Repeated spark plug removal on alloy heads creates tiny stress cracks in the threads on the heads - which get bigger each time.

Picture please before I comment on spark plugs.  It is so easy to give the wrong diagnosis, especially when 'black' plugs are described.

thanks for the quick reply dude, i only changed them the once from being serviced as my car seams to have developed a misfire or something and not sure if its a plug or coil, but its pissing me off now  that i could need a head now lol

If you've only changed the plugs once, and aint into the habit of changing them every 3k, then your head will be fine.  But if you have a misfire, you really need to get it scanned with VCDS.  Has any of the warning lights for the engine ever come on in the dash?

[x18wag]

the only warning light that came on was traction control and wouldn't go off, took it to vw and they replaced my abs pump. but this is when all my misfiring problems started they seam to think its a dual mass fly wheel but im not convinced, and my mate that works at vw checked for fault codes on friday and there wasn't any  and i don't know anyone up beside me to log my car lol
