NGK Iridiums BKR8EIX ***12k mile update on page 13***

Just read the whole thread, so many conflicting views  Still going to give them ago on mine

Sorry to resurrect and old topic but for me its quite current, so I thought I'd post my experiences.

I have 2007 Octavia vRS 2.0TFSI and the car currently has about 58k miles on the clock. I wanted to carry out some self maintenance and bought new coils and plugs from Awesome. The car had original Bosch plugs and coils and its been fitted with a stage 2 tune. My problem with the car has always been that every now and then the car has some trouble starting when its cold, so I figured that it must be the plugs. I've read quite a few topics about this and realized that cold starts is pretty a common issue for the TFSI engine. Therefore, changed the coil packs and the plugs and now it does it almost every single time. So, based on this I probably will be changing the plugs to either 7's or maybe even 6's. The problem is pretty much the same what gigolo456 had on the previous page.

Further to my earlier post, I can confirm that plugs had nothing to do with the start issue. It was actually the battery. Idle is definitely a lot smoother when compared to OEM plugs but other than that it is very difficult to feel the difference. I might still get set a of 7's as I feel that the 8's are a tad too cold for my daily commute (i.e. won't reach optimal operating temperature) and might cause unnecessary carbon build up.

So for a Stage 1 GTi (250bhp) would heat rating 6 be best?

Thanks

Sure is... although you need more of them than Iridium/Platinums.

I fitted the 8's last September and here is the result. Bought a set of 7's and installed them today so let's see how they work.



These were the OEM plugs that I took out and replaced with 8's. The OEM plugs had about 55k miles on them

Some carbon build up on the end of those 8s.

Indeed, although not as much as TT-Turbo had on page 13. Changed these since the past two weeks I've been getting odd idle when cold starting the car (we had -11 Celsius this morning). Other than that never had any other running issues with them. VCDS logs pressure drop between turbo an TB at ignition. Give it minute to settle, erase codes and all is good...

Oem for the win I think ! Has anyone actually took the OEM plugs out and thought feckin hell ?
Changing for changings sake I think. I'm going to pull a plug soon and check I think if they look good in be sticking with OEM

I agree. Currently idle a lot smoother but that's due to brand new plugs. I think I will order a set of original plugs before the summer and just stop there as I never had any issues with the OEM plugs.

My 8's have arrived 

[vRSAlex]

Stick with 7's imo.  8's are crap for day to day.  Foul up.  7's burn so much cleaner.

What he ^^^ bloody crap for day to day driving
