[iiball3]

This kid I know told me Bosch spark plugs..the iridium ones are bad for jap cars..I know obv. NGk would be boss..but he said Bosch top of the line plugs go bad quick and aren't good for Japanese cars..is this true or is he jus thinking he know everything..

I dont know for sure if it is true, but my local mechanic told me the same thing. He recommended AutoLite plugs.

I think everyone here is going to tell you to for with NGK or Denso spark plugs for our cars. I've heard diffrent things from Bosch brand and people say they suck for our car and Bosch is mostly meant for VW or Audi but to be honest I'm not 100% sure why there bad for our cars. just what o read maybe someone with more experience will jump in and explain.

i personally only use ngk as far as plugs and wires go. cant say ive had a problem with them and considering 3 years straight of new plugs and wires every 3000 miles thats pretty damn good

I've used Bosch Platinum+4 plugs in my H22 with terrible results. When I switched to NGK Irridium I could actually feel the difference (seriously... not in my head.)

Bosch o2 sensors are crap for our cars. They do not work. I think a lot of people assume that because of that one thing, everything Bosch makes is crap. That is simply not true. Bosch products are great... just not usually great for our cars.


I'm sure a basic Bosch spark plug would work just fine. The gimmicky ones are crap, at least for us.

Normal bosch plugs are ok but as deeve said the +2 and +4 plugs suck in my opinion. I only use NGK plugs no matter what it is I've had far better results out of NGK's than bosch.

I use E3 plugs and they make a huge difference running E85 gasanol, especially when its below 40 degrees outside

[deevergote]

E3 plugs have actually been the subject of many tests that have shown them to be absolute crap... though maybe E85 and cold weather is their strong point...

lol maybe, in a few days Im actually going to be pulling them out, Its been 2 years Ill check them and see how fouled or carbonated they are

[turbo90accord]

NGK only for me please.

I prefer NGK over Bosch. I have had Bosch in my old Volvo at one point and they did just fine (After all it is a Euro) but they tend to foul out quickly if your aren't careful. NGK's come stock in Honda's and so it is best to stick with those as others have mentioned above.

Gilly's 2 cents worth here.

Just question, why do you change them every 3000 miles?

[CB7Nub]

For our cars.
NGK is best, period.

This.

Hell, mine came from the factory with NGK plugs.

The only thing Bosch is good at making is wiper blades.

I'm using NGK iridium plugs on my S2000, and find that they hold gapping better than Copper or platinum.

AFAIK, copper plugs are still the best. Best power conducting but need to be replaced every ~25000km. Atleast thats when i did and noticed that they weren't in very good shape
