It doesn't matter much except for the life expectancy of the plug as long as the heat range is the same. I would go iridium ngk or denso. They are both good.
I had this happen before on a 2015 acura rdx. We thought it was the blend door or that it was low on r134a. The culprit ended up being the expansion valve in the dash behind the glove compartment.
When I had my acura rsx I did a lot of modifications. Usually one at a time. I remember they recommended getting urathane motor mounts because it would help with wheel hop. It ended up give my car small vibrations in the cabin/dash. Then I got urethane bushings on the control arms and got more...
I believe the correct part number is: N808689-S417. At least those are the ones I used to replace my rivets and they are the same size. By the way the rivet is big and you will need a bigger rivet adapter. I had to buy one from macmaster.
While I don't have this part, I have done modifications that change the factory bushing to urethane bushings. The vibrations from the engine or transmission are transmitted to the dash, chassis, etc. I am surprised that your setup is vibrating so much that it affect your driving. Unfortunately...
You should check if you are low on oil or if you have any oil leaks on the clutch cylinder. If the throw out bearing was bad you would hear a nasty screech sound.
That is normal, the o2 sensors readings are out of range since you removed your catalytic converter. I don't think a tune will fix it but i'm not 100% sure. You can add a defouler to each header which will make the o2 sensor be further away from the pipe.
What a great video and explanation. I already knew you had to torque suspension components while the wheels are the ground but I couldn't fully understand why. But this video clears everything up the great thing is that it applies to not just mustangs but all vehicles.
Let me be frank with you. A true cold air intake routes air from the outside of the car to the inside intake manifold. Those intakes are not true cold air. When I had my rsx there were 2 intakes you could buy, the regular straight ram air that would suck from the engine bay and the other was one...
I don't believe it takes 4 hrs to program an ecu. I think they are charging you more for the overhead of the work. Meaning paper, etc. Etc. I don't know if they have to do a lot of procedures such as key learning, but I am sure there are setting they can probably back up and restore. In my...
I am 41 and I can definitely say that the post above is true wisdom. If you can hold out longer you will be much further ahead later in life. I know it is hard because I have been there and committed the mistakes.
