comments on these Spark Plugs

[Mike1980B]

Ive had previously used Bosch Plantinum 4's in other vehicles with amazing results. was wondering if anyone had a take on these http://www.boschautoparts.com/sparkplugs/Pages/PlatinumIrFusion.aspx for only $6 bucks a piece Im willing to give them a shot. whats everyone think?

looks like there would be more to go wrong with them

back when I was spark plug shopping, I read some on those. The only people that were saying anything special about them was bosch. To me, there is just more metal around the center electrode that would shroud the spark from igniting the fuel. One benefit, i believe, is multiple spark paths when one wears down. I would (and have) done stock ac delco plugs (rebranded ngk iridium) with ok results. I just cant see a benefit with the bosch 4. What were did you see as an improvement when you used them before, mileage, power?

the idea of those plugs is a good one but it just doesnt work out as well. when u divide your spark into 4 like that, the spark is significantky weaker. the plug is putting out the same voltage no matter how many times you spark it. so basically, you get 4 weak sparks instead of one good strong one

i personally love the e3 plugs. i have used them in all my cars and in all my friends/families car. nothing but good things heard about them, better accel, and better fuel mileage.

Anything Bosch is junk IMO. AC delco will work the best. Alot of the plugs are just snake oil and I have yet to see any measurable gains on a dyno. YMMV

You want NGK TR5

Yet, how many parts on your car were supplied by Bosch?

You want NGK TR5

They don't go by that number anymore. They go by four digit numbers now. What is their's?

You do realize that ACDelco plugs are rebranded? My stock plugs were NGK.
