Spark plug Bosch or Denso

That's what I am running in my wife's 94 and the idle in her car is real smooth...

I run the F6DTCs and have great results with them

I've run NGK BKR7E's, NGK BRK7IX's, Bosch FR7LDC, and Bosch F7LTCR's. Of all of these plugs I noticed the best performance out of the F7LTCR's.

I switched to a Bosche plug F7LTCR $4.41 a piece from rockauto.com. They last 4 times longer, and run much better than the BKR7 series.

Bosch FR8DS plugs are stock aba (2.0L 8v) plusgs and are awesome.

I decided to go with the Denso Iridium Spark Plugs Part # 5304#4 and am VERY happy with them. My car runs better than it ever has. These plugs were a little expensive but still less than what the dealer wanted for OEM plugs. I definitely recommend them!

if you're gonna go iridium get the denso's because they (denso) have a smaller tip on them allowing for a "cleaner spark" and therefore a greater chance for detonation....less missfires as someone else has already said....I've run them both and I'm very pleased with the denso's

When it is warm out the IK24's work awsome. But on cold mornings they suck for the first 3-5 minutes of driving.

Platinum +4s are the worst plugs you can use. They have a bad habit of losing tips into the cylinders. I don't think I need to explain the results of that.

i've got some bosch silvers...and this happened after about 12k miles and currently (3k miles) later i'm getting similar symptoms as before.
