Just use what it's supposed to be used: Bosch F8DC4 (which replaced the one described in your owner's manual). You should be able to get them from PartsShop. Be aware NOT to use platinum plugs. When I replaced mine last time, I assume the gap was as written on the box. I didn't check the gap although I have read somewhere that suggested to gap every plug before installation. You should have a torque wrench at hand for correct tightness.
WOW, a 95 with just 30K miles. I had mine last May and she has 27K miles on the clock. After we took her to Yellow Stone and Grand Canyon and couple of times to the Bay area from Southern California, it's 47K now. Have fun with the car.
