I know GM does not require changing spark plugs until 100k, but I am going to change them at about 50k nonetheless. From what I already read from searches, many members feel that sticking to the stock plugs are the safe way to go...but I'm going to screw around and try something else anyway. My question is: does anybody have any experience with either Autolite XP's(#XP 605), AC Delco RapidFire's(#8) or the E3's(#E3.62). I'm going to try one of these three types, and while opinions are welcome, first, or even second-hand experiences with any of these plugs are preferable.

stock plugs will benefit your car the best.

I have seen this information, try looking in the performance section. Don't forget to have the search look in post bodies as well as titles, and set the date range for "All Dates" or a long time back.

Sleeper style, they don't see it coming that way.
I have lots of experience with plugs (working for a local parts store for 4 years will do that for ya). I have never had good luck from the rapid fires, I put those, all 3 types of Bosch Platinums, and the stock ones in my 95 2.2. I have had the best results. I have been wanting to try the Delco Iridum. Most people dont know about these. They are the Delco Platinum number "41-101" They are in the platinum section, but they are actualy Iridium. The threads are the same, but it is about 2 threads shallower. The great thing is they are only 5.99 (beats the hell out of the 12.99 denso iridium) If you are wanting to try a new plug, try these, let us know how they work.

What makes you think I'm crazy?

Did that, searched "all sections" & "all dates" - all I found was one or two short comments on the RapidFires(colder #5 plugs) but no info on the other two types. Granted, I think they are
relatively new models of plugs. Thanks for the tip though!

just remember, rapid fire +4 all that crap is just marketing garbage they come up with to charge you more for the same plug. If you want a benefit, spend that extra cash on something like an MSD. Electricity will choose the shortest path no matter how many paths you present it with.
Soooo.... ACDelco Plats are the way to go. $5.99 a piece at my local autozone.

I gather that most everyone thinks any multiple ground electrode(Bosch +2, +4) spark plugs suck, and it seems AC Delco RapidFire's aren't so great either. Anybody have any info on Autolite XP's or E3's? The Autolite's look good because they have a "iridium enhanced" .6mm finewire center electrode and a single platinum ground electrode. The E3's could technically be considered multiple ground electrode plugs, but the difference it seems is that the electrodes are all connected, unlike the Bosch +4. There's also a diamond shaped opening at the top of the electrode so, instead of shrouding the flame kernel, it can fire towards the cylinders...or so they're advertising says...

Those E3 plugs are available from my local Lowe's....
They're only available for my lawn equipment...
They're fantastic ! .....
J C Whitney was supposed to have them for Cavaliers...
They don't anymore according to their website...
Can you give us a source ? ...
