Installed New Plugs & Wires

I have a 1986 Lxi I recently acquired from a relative.

Pulled up on plug wire #1 to check the plug's condition, and the metal ground inside the boot tore off and remained on the plug. Now I needed to buy some plug wires as well.

Today, I gathered some NGK BCPR6ES-11 plugs that I had laying around. They are not the stock BPR5ES-11. The stock use a 13/16 spark plug socket and have a heat range of #5. The plugs I installed were a colder plug (#6), but I didn't want to spend more cash and decided to use them along with a brand new set of NGK plug wires.

The plugs were replaced easily and I used some antiseize on the new threads. The new plug wires had a resistance of 2.6K -5.6K Ohms. However the no-name brand (BWC) I replaced had a resistance of 1.34K Ohms. How can a cheap brand have a lower resistance than NGK's?

Anyway, the car starts better now. Hopefully, after I change the air filter, the gas mileage will improve. Do you guys think that by running a colder plug there will be any problems in the future?

First off, did you measure and compare the same plug wire length? For example, did you measure by mistake BWC #1 , to NGK #4 spark plug wire?

Also, if you had Borg Warner Select Nascar wires with mag core, they are supposed to be low resistance wires.

Also resistance of plug wires aren't everything in terms of performance. EMI and RFI rejection is also important. Visit www.magnecor.com to learn about plug wires.

Running a colder plug than necessary, a possibility that the plugs foul up and carbon deposits faster because the tempurate is not hot enough to keep the plug clean. All you have to do is change to plug more often.

I hope this is helpful.
