Hello getting ready for tune up.
What are the best sparkplug wires to run on a 97 s-10 blazer.

 

As we've discussed before, best - AC/Delco; good enough - any high quality wire set.

 

We've covered that before? Wow, even lets say ... shackle lifts, TB twists & my favorite - what tire fits bla bla bla lol?!
Any good quality spiral core or 7MM or better (that fit in the wire jackets) with at least a 3 year warrenty will do a good job.

 

AC Delco. Also do the cap a rotor.

 

Yeah stick with Delco, Delphi... these vehicles are picky for electrical. Odd I know but search here & read!
For wires I have 8mm Bosch, but my engine isn't normal is all.
BTW they have a 5 year warrenty for my application.

 

Don't run beldens.
