Platinum of rapid fire plugs?
Which would be better for my bone stock 305TBI? I was wanting to go with a little bit better plug than stock. Thanks

I got the AC Delco Rapidfires (25THRSS is right, they are platinum). I'de recommend getting 'em, I've had no problems. BTW I also have a (near) stock 305.

Hi LilJay,
I tried the Bosch brand platinum spark plugs a couple of years ago, then switched to ACDelco Resistor copper plugs. I've noticed that my car (see sig below) has reacted much more positively to the copper plugs than to the platinum plugs overall.
Hope this helps!

Plat plugs are disigned for newer engines with coil on plug ignition, I think. Either way stay away from plat plug you dont need them, and they nothing for our engines. If you wanna work on Ignition system try a higher output coil, better wires, maybe MSD

Basically Plat plugs are meant for distributorless ignitions. In an engine with a dist. they will harm performance, stay with copper.
I just got off the phone with brother who is a mechanic. He mentioned other info but i couldnt hear him.

Car: 89 T/A
Engine: 305 TBI (Hopefully LS1 someday)
Transmission: 700 R4 (T-56 is planned too)
I took a set of Bosch platnum +4's out of my 95 3.4L Camaro and put in Accel's top of the line brand. The next week I was ripping the brand new Accel's out and buying a new set of Bosch Platnum + 4's! There was that much of a difference! Now, I put a set in my 89' 305 TBI T/A, but didn't notice a difference over the stock AC delco plugs. Engine runs like crap either way. lol, I'm just waiting for it to die so I'll have the wifey's approval for a LS1. By the way, the Bosch made a huge difference in my wife's Nissan too.

So performance wise there wouldn't be any different than the regular AC's?
