Stuttering in 4th@WOT

45k on my car, had 5 sets of plugs since 20k. I bought the car with 17k on it, I have some seafoam to try out and I'll see if it makes any difference.

not a real fan of seafoam on this car, it doesnt do as much as people think for cleaning the valves. Some of the carbon needs to be pokes at with a pick to come off.

what do these plugs look like when you take them out?

Looking at pictures on the Internet, they look normal. This one was from with the hypertech (stock plug)

and all four appear the same each time you take them out?

Yes, no signs of damage, overheating or fouling.

Changed the plugs today, they all looked like this-





I did a seafoam treatment yesterday so I'm hoping that's what the red colour is. Also whilst cleaning the maf I noticed this








I take it I'll have to buy a full maf sensor from the stealers?
On the plus side, the car runs great now. I'll give it 6 weeks before I have to replace them though!!
