Good old copper ones as LF1 mentioned should do the trick. Dan at the parts counter (Mazda) will also urge you this way too. Welcome back!!

I agree w/lakersfan1... w/one exception. I started running "halo plugs" in my MX-3 3-4 years ago. Rated for 100K miles under normal use and I still have the original set in there 50K miles later. I was so impressed, have also installed em into my '90 MX-6, '96 626, '95 Camry, '92 Celica GTS with great results. Halo's are expensive (currently $9 USD ea.) and went out of production for most of 1995 but they are now available again. I think it was U of Michigan that did some tests a few years ago on a variety of spark plugs - you can probably find the UofM link on the site-linked below. I remember that Bosch plat-4's were one of the expensive ones tested against standard copper plugs. The plat-4's showed no increase in power, responsiveness, or gas mileage compared to a regular plug. The plat-4's did provide a longer lasting plug and that was their only measurable diff. The Halo's were the only plug to show performance and mileage improvements over the others.
To validate the results, the testers then took off just the "halo" and replaced a std. copper plug's sidewire with the 360* halo tip. The copper halo-modified plug showed similar improvement. Researchers concluded that the halo tip shape was the difference. When I installed in my MX-3, it was one tank of gas after a 100% complete tune-up (with NGK's). I swapped out the NGK's for Halo's and the "seat dyno" reported a smoother idle, quicker and stronger throttle response and best of all, my mileage on the next tank of gas under virtually identical driving conditions was 3.3mpg higher. I'd run NGK's or Denso if I wasn't using the Halo's. Here's the link if interested. (btw, halo's are not good for turbo'd or superchged. motors) http://www.haloplug.com/faq.php
Sorry for long post. I called out sick today so am rambling with the time.![Rolling Eyes :roll:](./images/smilies/icon_rolleyes.gif)

Thanks for the info
I checked out the site, the Halo people have a lot of good info there, more people should check it out.
Never heard of halo plugs as far as the bosch+4's I went from NGK to the +4s and did notice a lil diff. in power gain dunno maybe cuz my old plugs were going bad. Altho I will mention that after installing I also noticed a loss in gas milage get round 250-275 miles to the tank depneding on what gas I run.
