Spark Plugs

[Jaywoo-GTI]

Looking to upgrade my plugs to iridium items, Either NGK or Denso as i have used them in the past with impressive results.

Does anyone have any other good upgrade/recommended plugs or even the part numbers for the plugs i should be looking for?

Also what manufacturer and part number are standard VW items so i can X-Ref them?

Have a look at these mate. There have been some real good things being posted about them. Also have a look on the site with the demo on how the flame front moves http://www.pulstar.com/ignitionvelocity.htm There is some real interesting stuff here. With these in place you could advance the timing quite a bit which would increase BHP and Torq.

Are you stock or remapped?
If stock, stick with the oem plugs.

[Jaywoo-GTI]

What are OEM plugs?

Its stock at the min but is goin in within the next month for a remap so looking at gettin everthing i can first.

The good upgrade plugs are NGK Iridium BKR7EIX. They are one heat range colder. The BKR6EIX are a direct replacemnt. These are highly recommened by alot of people. I use them myself on my stage 3 car.

To those in the know: Would these be beneficial for my Stage 2 GTI ???

JKM, VWR, and others have all advised me that I don't need to change plug type on my Stage2 GTI. I change plugs every 20k miles but to the same oem ones.

....But you best know exactly what you are doing if you are going to do things like big timing advances. You may increase power but what else will be going on? Would you then, for example, need an aftermarket fuel pump?

....I found it interesting but not convincing.

Yes, I am definitely not convinced on this one. At the end of the day detonation is detonation, irrespective of the strength of the spark.

OEM (Stock) plugs are fine on stock and remapped cars - no real 'need' to upgrade them - just swap them more often than normal if remapped.

As for altering the timing, this maybe so but you need to do some data logging to make sure your not making the ECU pull the timing back too much - all about the CF values and keeping them low.

I have never really understood heat ranges, What does a colder plug mean?
