First of all, I decided to go with NGK TR55's and Taylor Spiro Pro 8mm's.. My questions are these:

1. Do I need to re-install the factory heat shields on the wires?

and

2. Are the NGK TR55's pre-gapped?

Let me know guys, thanks in advance.

 

1. no you dont have to re-install the factory heat shields

2. the NGK TR55's are pre-gapped at .54
the factory gap is .60 but i think a lot of people run the TR55 at around .54

 

FYI, you don't have to put on the heat shields, but they do fit and I don't see how it could hurt.

 

Thanks for the replies thus far.. Any other opinions on the NGK gapping??

 

Well just for the record, the Taylor wires don't fit into the factory heat shields. Let's just hope I don't need 'em.
