iridium are longer life plugs, there sparks not as good as oe, there better for newer engines that are designed with this in mind (mazda 3 springs to mind, 60 quid for a set!)

get a set of nology silvers, recommended by r tech so good enough for me

??? how you get that?

i was gutted i had to pay that much, and in the end it turned out it wasnt the plugs causing the miss, the egr gasket had perished and made it sound like it was running on 3 cylinders, my stupid fault for leaving old gasket on when i had engine out

mapped cars should run a colder spark plug no ?? I read for ages before getting my plugs and was told every 50bhp increase should be a range colder plug.. so normal iridiums are IK20 and then one colder was IK22 which is what i got.. it may be rubbish but a few sites said this when i was researching..

Also the plug VW use is fine  :smiley:

honestly mate from experience I've had so many customers come in spark plug faults. Replaced whatever make of plugs in there with oem plugs and they've never been back since.

My cousin had a remap on his S3. Now 3 weeks prior to the mapping he fitted some high performance plugs(forgotten the brand). 2 weeks after the remap he developed the misfire and i diagnosed it down to the plugs. Replaced them with some oem items and been fine since.  This was nearly a year ago.

From my point of view when it comes to the mk4 and onward model golfs only oem plugs can really work in the engines. No doubt other people here will disagree but this is my own say on it.

First posted iridium electrode spark plugs re: 1.8T 8yrs ago eu & us forums.
time to update: denso & ngk iridium plugs SAME production line / physical factory in japan - no change

Originally denso IK20 basic street heat range - now update to denso IK22 basic street AND mild tuned 1.8T - IK20 runs slightly hot in typical high summer temps worldwide

this means detonation will be detected and timing retarded (pulled) randomly street driving - solution use slightly colder denso IK22 as street plug EXCEPT during genuine low temp winter conditions - for this use denso IK20 only winter conditions, than change to IK22

re: 1.8T spark plug gap - ONLY gap to 0.028 inch or 0.7mm DO NOT increase gap as excessive discharge arc current will cause coilpaks to over heat and fail - I have posted this data for 9yrs and remains valid AND included hitachi coilpaks fitted a3q/s3/s4 varients and mk4 1.8T

denso IK22 is nominally (close but not quite) factory gapped 0.0288
and can be lightly tapped to close down to 0.0275/0.028

denso IK20 factory gapped to 0.038 and MUST be adjusted to 0.028

denso IK24 only recommended for fully developed engine / BT and is not suitable for prolonged slow crawling urban traffic conditions

while many prefer conventional spark plugs, iridium electrode plugs give consistant discharge arc joule levels without fouling during street driving / immediate engine response

if you experience detonation problems due to unresolved f/a issues USE conventional spark plugs as centre electrode + earth strap more robust and resistant to mechanical shock - and sort out your ecu mapping or add water injection

there remains on-going perception that nippon denso heat ranges are slightly different from ngk heat ranges re: iridium electrode plugs - in reality same with proviso that you have access to fully product line of each brand, this varies from country/region

So for my mk4 golf 1.8t 1999/AGU my spark plug gap will be 0.7mm??   I'm currently running a 1.2mm gap :/ and experiencing some tempermental lagg. Will this be my problem.
Please confirm spark plug gap for my golf :')

THANKS!!
Title: Re: spark plugs
Post by: rockmonkey69 on 12 December 2014, 20:00
Standard gap should be closer to 0.7mm and not 1.2mm
Title: Re: spark plugs
Post by: MarcIV on 12 December 2014, 21:42
Should I change them to .7mm?
Title: Re: spark plugs
Post by: rockmonkey69 on 12 December 2014, 22:57
Some plugs cannot be gapped, check your set are fine for gapping first, or alternatively purchase a set that comes pre-gapped to 28thous (~0.7mm)

Just would like to tell everyone that reads this thread in future that my plugs were at 1.1mm and I suffered from dip in acceleration almost as though my car was holding back, So I changed the gap on my spark plugs to 0.7mm and my god she pulls well instant throttle response! Think she's back to 200bhp :')
Thanks guys!

1.1mm is only good when you have mk5 coil packs on the 1.8T...

I see, I have Bosch ones. Don't think there mk5
