Bosch Plus 4 WR76 spark plugs

[Dieter H. Marschall]

Hello everybody,

in my TR6 I use those Bosch plugs and I am very happy about them. They have four electrodes.

Would they be of any use in a Stag engine, too - or just a waste of money?

Best wishes,
Dieter.

I use bosch super4 in my rv8 range rover. Huge transformation running on lpg but no difference on petrol.

Now I mainly run old British bikes, its a lot easier on a bike with an engine exploding between your legs to detect differences that it is in a car with all its methods of insulation.

Now since 1976 I have tried every fancy sort of spark plug going including these Bosch plugs and have never noticed the blindest bit of difference in any of them apart from that NGK are crap.

Until that is, I tried Denso Iridium, these do make a differnce, they make my Triumph Trident run like a sewing machine, I was so impressed with them that I used to pay £16 each for them for the Stag, and the X pack Essex V6 I had in my Vitesse.
Fortunately now I find them online at a very reasonable price:- http://spark-plugs.co.uk/index.php/p...tails/IW16/343

They also have a wider heat range so on my rather more tuned bikes, I no longer need to put softer plugs in for the winter.
