I will be changing plugs soon and I was wondering what you all think about the bosch super 4 plugs. I use to always wonder why plugs only had one electrode. These seem cool but does anyone have experience with them?

 

stick with NGKS

 

It may be NGK bias, but I've had a couple technicians at different shops tell me the Bosch plugs are crap & should be avoided.

 

yeah I have used the +4 before on my 3rd gen and the plugs were fried in 2 weeks they did seem to get good spark but then again a tuneup always makes the car feel stronger .

 

ive read that the VQ SUCKS ON Bosch 4 plugs. infact i think i read that it messed up the engine in some way. if i were u i would buy some NGK's: copper or plat

 

Stay with the OEM plugs. I had the +4's at one point and the car was absolutely gutless with them in.

 

Go OEM or get the much cheaper copper NGK replacements and change them out every 20-30K.

Okay NGK it is then...thanks for the feedback.

 

weird....i have bosch super 4 and i felt a very good test on my car and dont have any problem after 8 months.

 

i tried them and noticed absolutely nothing out of the ordinary one way or another...no hesitation or misfiring but no god forsaken improvements either...i think i understand the potential benefits but i dont leve plugs in long anyhow so it's not cost effective.

 

same here. nothing beats stock parts (IMO)

 

I noticed lethargic acceleration above 5000rpms, mild detonation at 5500+ rpms, and overall more buzzy feel. I never thought spark plugs could make such a difference in the way a car runs. There is a saying that you should never run German plugs in a Japanese motor.

And again for everyone that missed out or needed the part #s:

NEVER EVER RUN BOSCH SPARK PLUGS IN A VQ!

 

I just changed my sparkies yesterday using ngk coppers.
Only cost me $11 bucks and now my car is running a lot better than before. Its cheap so stick with the coppers if you don't mind changing it more often.

 

One thing Ive learned from Japanese cars is that they dont like German Parts. (Good Example) Its like taking one of your fingers off and puting a monkey finger on instead

 

lol.....thats a good example
