So my car is just hitting 80k miles. I called my dealership, where I have had all service done up to this point (I have the extended maintenance plan, which expires in one month) and asked when/if my plugs and coils have been changed. My plugs were changed in December, but they said my coils have never been replaced.
What is the normal interval for coils? I thought around 50k, but apparently not?

I am considering trying out the MHD tune, and they recommend changing out the plugs and coils first and gapping the plugs to .022. Since my plugs were just done, they don't need replacing, but what is the stock gap? Isn't is around .025?
Do the plugs come preset to recommended OEM gap?

If I get the MHD and replace my coils, I can just re-gap the current plugs.

This should be fun - last time I changed my own plugs was on my '93 Saturn back in college over 20 years ago.
