I used them for a while with a .55 gap and the car ran weird (especially with the ac/defrost) It felt like it struggled after stoplights and in warm weather. I went to motor craft double platinum recently and it feels much better. Just my experience with them though. (All i have is a steeda sri and muffler delete right now btw)

There is a very special way you have to gap the AR series plug and I have never seen anyone with the correct tool to set the gap , the gap shouldnt of been changed and more then likely you were over .065-.070 because the gap isnt set the same with the wire cut back , its a mistake many make

By your description thats exactly what happen

I have the $70(?) Massive Speed 75A Street one, it’s nice and quiet for daily driving and only causes slight vibration when AC is on. Way tighter shifting than stock. Every time I drive my sister’s stock 5-speed 2009 SES it feels so sloppy, then I get in mine and it’s like a different car.
Might I add she only has 70K miles and I have 150 :cool:
