Bosch vs NGK plugs?

[wormwood]

Bosch and NGK spark plugs for my blower cost the same.

Anyone have a preference one brand over the other?

Thanks.

Blower is a Stihl BR 420 D

Gentlemen, as always....Thanks!

i run ngk or denso in my stuff including my own and customers german cars. i dont know why--they just seem better. dont notice as many misfires or coil packs go bad w/ them. yet i have no concrete evidence as to why they are "better". just my gut feeling.

My dad has a Toyota Tacoma truck and had a local shop replace his plugs a few weeks ago. The shop used Bosch. On the drive home to where he lives (he was at his vacation house when he had his plugs replace), one of the coil packs went out. He took it to the Toyota dealer who blamed the problem on the Bosch plugs the independent place put in. Dad was told, for some reason, Bosch plugs cause all kinds of problems in Toyota trucks.

Sounded like BS to me, but they fixed the problem, replaced all of the Bosch plugs and the truck runs great again. Dad's had the truck since 2000 or 2001 and it has 130K miles on it and this is the 1st repair (other than routine maintenance) he's had to do.

Best bet is whatever is OE for the application, which in this case is Bosch.

 

[treasureseeker]

Bosch for German and NGK for Japanize vehicles.

 

[DrkMtnDew]

you probably would never be able to tell a difference. i like both. sounds like the group vote is NGK so there it is.

 

[5lima30]

FWIW my Husqvarna chainsaws like the NGK plugs. I've tried others which didn't last and fouled easily. YMMV.

 

[american lockpicker]

I recommend Bosch but I'm a Bosch fanboi at the moment...

 

[Lotek]

When I built my 912 motor, not being the complete German cognoscenti, I put Bosche plugs in, even though all my GM veh run NGK or AC, ran like ****, fouled, asked the guru , was told to run NGK, go figure.

I'd put what ever it came with from the factory back in it. Everything always seems to work just fine doing that. Just like it did when it was new.

And before someone jumps in and I start hearing all of the better mileage and better power arguments from everyone for any specific brand of plug, think of this:

If one plug brand delivered more mileage and better power and lower emissions over the factory plug, don't you think that that GM, or Ford, or Chrysler, would have spent an extra quarter a plug when they build the car and used that aftermarket wonder plug rather than spending untold tens of millions of dollars in research and development trying to comply with the Govt emission and mileage requirements?

Hey, at one point, the "greatest" aftermarket spark plugs you could buy had a radioactive isotope on the electrode because it improved the intensity of the spark and helped it to file are a lower voltage.

At another point, they had two gaps to fire across. And then eventually, three gaps. I've even seen a plug with four gaps.

And amazingly enough, the factory single electrode, single gap AC spark plugs in my Buick looked pretty decent at 110,000 miles when I changed them a few years back and were still delivering an easy 29 miles per gallon on the highway.

It wasn't all that long ago that the expected life of a set of automotive spark plug was 12K miles. Then it was 30K, then 50K, and now 100,000 miles. The increases up through the 50K mile mark were due to better fuel formulations, better ignition systems, and better air/fuel management. The jump to 100K miles was all of the earlier improvements with the addition of platinum tipped electrodes on those standard old dull and unexciting OEM spark plugs.

Aftermarket spark plugs are probably an even bigger business than ***** pills. As a result, you can expect similar "claims" to separate you from your hard earned dollars. More power, better mileage, fatter spark, multiple sparks, longer life. Just change "spark plug" to "*****" and the same commercials and marketing slogans apply.

Don't get me started on oil additives...

Hmmm, I feel a lot better now. I don't think that I'll need my medication this afternoon.

I'd like for all of you to keep using Bosch plugs in your cars; they bring work into my bay and put $s in my pocket.

Bingo! And it just always just seems to work out for the best that way.

I always use denso in my tacoma

[Virgil Cain]

I like NGK followed by Denso. Bosch Platinums have caused issues in a couple of vehicles I've tried them in, which is disappointing since in general I'm a Bosch fan. Back in the day I used regular Bosch plugs in my air cooled VWs and they worked well in that application.

 

[StarsofPleiades]

Ive always had good luck with NGKs in Subarus as they are the oem plug manufacturer, where Bosch will cause a misfire even when correctly gaped. But Subarus have picky ignition systems as well

 

[wafrederick]

Bosch spark plugs are junk,I see them after removing them and they go in the garbage can.Had a Ford Taurus that ran bad come in.Had good spark and compression.Checked the compression with a compression gauge.Looked at the spark plug removed and it was a Bosch plug.Replaced the spark plugs and it ran great.Same with a 1999 Plymouth mini van,had the check engine light on and it was a missfire code.Pulled one spark plug and again it was a Bosch spark plug.Replaced the spark plugs with Champions and the missfire was gone.Bosch spark plugs cause problems in GMs and Chryslers too.Dealer brought in a Chevy blazer that would not run,replaced the cap and rotor and found out why these two parts went bad.Pushed it in,still would not run and removed every spark plug: Bosch.The Bosch plugs went goodbye in the garbage can and replaced with AC Delcos.Ran good after that.

i also found out that running the copper NGK's and changing them every year work a lot better in the subies

 

[thesilverone]

NGKs in all my cars

 

[ngk22r]

I think my username is biased to....

NGK

 

[shampoop]

ngk ngk ngk. All i'll ever use. Every other brand you hear from some people that they're terrible, but never about ngk. I've never heard anything bad. ever.

 

[Toolhorder]

NGK for Honda, Denso for yota
Bosch Plat. 4's are GARBAGE. They cause misfires in lots of makes.

 

[Moose-LandTran]

Bosch for German and NGK for Japanize vehicles.

Not always true, lots of German cars use NGK plugs from the factory. Got some original BMW plugs for an E46 M3 the other day and they were NGK.

 

[btbsandman]

NGK is in all of my internal combustion engines.

 

[Farmrod]

used Bosch platinum 4's in my T/A and they worked great not so much luck in any other vehicle though if you are putting it back into a stihl then use Bosch that is their factory plug always stick to what comes in them from the factory usually cheaper and easier that way

 

[psychoclaw84]

NGK

All my small engines have been replaced with NGK if they are not OEM. I have no problems with start up's & performance. They are:

• Honda Lawnmower
• Karcher Pressure Sprayer with a Honda Engine
• Ryobi blower
• Echo Weed Whacker
• Echo Chainsaw

I have used champion (all variations), bosch and E3 and none of them work well in my small engine equipment. NGK have a nice operating range where they are less prone to fouling and temperature variation.

 

[GSteg]

I've never had much luck with Bosch plugs. It's either NGK or Denso for me.

 

[tw33k2514]

Never had a bad NGK before. So I would go with that.

 

[Eagle Point]

I always use the OEM plug and never a problem. Seems like the later model cars are very picky/sensitive to plugs causing missfire and tripping codes. Racing applications are where you may be able to use different brands. I remember back in the 70's I raced a Datsun 510 B-Sedan at Laguna Seca and Sears Point and the plug of choice was the Champion N59G, special order race plugs. In the stock 510 the NGK BP6ES was the OEM plug that would work best yet customers and "cheepo" tune-up shops would install Autolite and Mighty brand plugs causing a basic car like the 510 to run poorly. Stick with what the manufacture says for the most part.

 

[d33pt]

NGK in all my cars/trucks/motorcycles. never had a problem. I alway use the standard NGK plugs, but the RAV4 requires the $6 iridiums!

 

[SMKS]

I just installed platinum NGKs in my Nissan Frontier this weekend. About $3 each and made in Japan. Seems like a good deal to me. It had the Iridium's before, but with 140k miles, I decided the Platinum were good enough.

I haven't used Bosch, but I don't plan on trying them. NGKs work well for me, and if it ain't broke, don't fix it.

Does anyone know what the country of origin is for Bosch plugs?

 

[vssjim]

Germany or India
India for small engine and odd ball standard plugs

 

[4x4gearhead]

I have always had good luck with NGK though I put some bosch quad fires in my f-150 a couple years ago and they were great.(A bit pricey though and not gapable as far as I know.)

 

[rapyoke]

Bosch has let me down a few times, NGK has not.
