Default Which plugs and wires for a delco igntion?

I just got the delco igntion from a 1997 Buick installed on my 1990 Bonneville. I still have a slight miss. Since the plugs and wires have been on the car since I got it (25,000 miles, 17 months) I figure they should be replaced. Which plugs should I use? I don't need anything high performance since the rest of the engine is stock. Also, what are some good wires for this set up?

Thanks!

NGK TR60'* for the plugs. Gap 'em at .060" even though you have an upgraded ignition.

The 8mm Belden'* have good reviews. You can get them at NAPA, just get 'em for a '93, that way they are routed for a Delco Ignition Car [will fit better].

Yes get the wires for a 93.... Also Autolite Professional wires are good as well..

I have been using NGK TR55'* in both of my cars with good results..

The NGK TR55'* are only one range cooler... I have yet to have any issues with these and they seem to work great with the Type 2 ignition... They are about the same price as AC R44LTS6 or R45LTS6... Good Luck

I use AC Rapidfire #14s gapped at .060" with the Delco ignition on all of my cars. Frankly the only time I have seen a dead smooth idle was on a badly retrded engine.

I used the normal AC Delco plugs with my Delco ignition at 0.060". They've been great so far, and after I clean my IAC my idle pretty much sits at 600RPMs dead solid.

i use the bosch platinums. that put the life right back into the taurus gl. i just drove it tonight and noticed that beyond 25 in first gear the thing pulled like there was no tomarrow, up until it shifted, throwing you back into your seat <not the back seat, we leave that to the SHO>. they are like 2 bucks a piece down here, deaming them worth the money.

Is that the engine is mentally incapable? Or that the timing was retarded? I would appreciate it, if it is the former, to call the engine "special" Okay? Thanks .
