Bosch Super 4 Spark plugs

Was in Halfrauds earlier and decided to use my new shiny trade card and bought a set of the above plugs for my Fronty. I put them in this afternoon and went out tonight to Glasgow in the car and the difference is quite noticeable.

The car seems a lot more responsive right through the rev range was quite surprised to be honest. The plugs I had in were either duffers or these are pretty good plugs . Anyone else tried them ????

I have tried them and never noticed any differance to be honest. You are still only getting one spark and 9 times out of 10 they are bought to replace tired plugs anyway. But as long as your motor is running sweet, thats all that matters. Be interesting to drop a new standard set back in to see if it feels worse.

as you know the spark takes the easiest route to earth so there will be only one spark but as it has 4 choices it will almost always choose the bbest spark . tbh tho i'd doubt if they were any better than manufacturer's recommended plugs
