hELLO I HAVE A 1991 FORMULA 350 AND I WAS WONDERING WHAT SPARK PLUG WIRES I SHOULD GO WITH. i RECENTLY REPLACED THE CAP AND ROTOR AND NOTICED A FEW OF THE WIRES WERE CORODED AND LOOSE ON THE CAP. I ALSO REPALCED THE SPARK PLUGS. i AM A LITTLE CONFUSED WITH ALL OF THE ONES ON THE MARKET. ALSO IS THERE REALLY A NOTICABLE DECREASE IN PERFORMANCE IN 7MM WIRES?

ALSO THE ENGINE HAS BEEN RUNNING A BIT ROUGH IT SOMETIMES STALLS OUT AND THE RPMS KINDA GO UP AND DOWN A BIT (INSTEAD OF IN GEAR IDLING AT 700 IT GOES ALL THE WAY DOWN TO 500 AND BACK UP) I LOOKED FOR VACUME LEAKS AND HAVE NOR FOUND ANY

THANKS

 

i like a/c delco rapid fires for plugs.

and i use accel 8.8's plug wires. since i needed 90 degree boots for my header install.

trying running a search on difference brand names like a/c delco msd taylor accel bosch to see what others think / use.

i tend to buy tune up parts that are in stock at my local parts store for a good price.

stock oem size wires should be fine to use with stock ignition / engine setup's.

 

I run AC delco R45TS spark plugs in my 350. And I also run 8.8 accel wires because I also need all 90 degree boots for my headers.

I would go ahead and change the wires it definetly won't hurt anything.

 

Pretty much any wires you go with will be an improvement over stock. You won't hear many complaints from any particular brand.

 

NGK for plugs, you can find them at NAPA.

 

try pressing the cap lock button, things will work out a lot better.

 

he's new let him stay

 

aha didnt mean to offend anyone with the CAPS lock on but what the heck a quesiton is a question no matter how it looks.


Thanks
