Ok finally decided to get into changing out my spark plugs, so far I only have 1 out and I receive a big surprise when removing it. Nope it didn't break off, I have Autolite HT0 plugs in the engine, the engine previously from original owner was turbocharged so that explains that. So I am going to continue with removing them since I am still N/A.

 

Definitely want to replace with HT1s to have the proper plug. Good catch!

 

The gap is probably wrong as well from having the HT0 with Turbo setup. I believe they have to be set at 0.035 to 0.038 for Turbo vs 0.045 to 0.054 for OEM.

 

The gap on the HT0's were definitely set for a FI setup, I could notice just by looking at it.

 

I bet it runs way better with the ht1's gapped correctly.

 

I will find out I just took it out for a short drive to make sure everything was running smooth. Curious if this will help out the mpg's or performance at all.
