Hi all,

I'm due to pick up my bocanegra on Thursday 2nd hand, 2010 plate. I have gone through the history of the car and its had the waterpump replaced and has had a recall done on the brakes (not sure what mind).

I have been reading all about these misfire issue and to tell you the truth im pretty worried. Car has done 19,000 miles - im hoping most of the issues will have been ironed out!

Out of interest at what age are people getting issues with oil consumption misfires etc - do they generally happen when new (ish).

Anywho back to the question i have read that these NGK BKR7EIX spark plugs are the ones to have in the standard engine even if not mapped. Do these plugs have a different gap setting to standard, i know they run cooler but just concerned if i need to regap them or is it a simple switch over?

As the car is still in warranty - would it be frowned on if i changed to these do you think.

I just want to pick the car up, ensure i'm set with fresh oil + updated ecu/dsg software (dealer is doing this) but when i asked about the spark plugs they looked puzzled so i was just going to do it.

Assistance much appreciated.

p.s previously had the leon mk1 cupra tdi... i've been away for a bit as a had a clio 200 - but running costs have started to hurt so i've hunted for something in between :)

I'm running bkr8iex gapped a 0.65mm which is a grade cooler than Revo recommend 2 cooler than standard and were fine in my unmapped car although I'm now stage 2.
7s will be fine. Make sure the oil you use retains its viscosity upto 120c if your airing on the side of caution.

Mine happened to come like that but always worth a check.

I've tested the 8s for about 2 months. 6 weeks on unmapped car and 2 weeks on stage 2 Revo. Car never missed a beat with them in.
