Uprated Spark Plugs Thread.

I have no idea when the plugs were last changed in my Golf, a good couple of years ago I should imagine!  I may look into some of these soon, £12 each is a tad steep though.

not to bad  i suppose its like anything well mostly you pay for what you get iirc my iridiums were about 40quid

These arn't the plugs that Nick has advised,he gained a fair bit of power from the Nology silver tip spark plugs.

The nology silver and Bosch super 4s plugs are what we use at the moment.  We have tested coil pack which made greater power over oem but the cost to have them produced was ott.  Plus we have tested some new plugs from USA which use a capasitor technology in side the plug to produce a greater spark. When fitted to Bens AUM the smooths a inhertent flat spot out and gave another 7bhp avg over the Bosch plugs.  I will get the graphs dug out.  We need to find some time and play a bit more with these plugs and comapre them back to back.

This is very impressive,i assume that the plugs removed were in good condition? What plugs were they Nick?

[RTechUK]

They are very good plug, we also had some good results on a few MK2s and a Mi16 on 45s carbs.

We want to find the time to do back to back runs with a few sets of brand new plugs.

nick how bout adding iridium densos? to compare with the other two  may have to change plugs over dependant on what you n ben evaluate from comparison?

[(shakey)]

Not much yet,

Back to back with super4s they make a huge gain in performance which can be seen on the dyno overlay but not felt on the road.
