I installed the Bosch double prong platinum plugs in my 06 Sentra at 97k miles. I now have 158k miles on them.
I have had no prior experience with these plugs.The car runs just fine.
Am i good for awhile?
Most of my driving is highway.
Thanks,
 
They should be fine. And even if they aren't, the plugs are easy enough to change in that car

You can push plugs pretty far but I'd change them to NGK Platinum or iridium if you have the money. Bosch plugs seem to be the worst among most engines Idk why. They made my Taurus idle funny, I tried the Bosch Platinum, Platinum +4 and Bosch ir fusion before I just went with autolite double Platinum and problem solved. Nissans like ngks.

Probably true for non-German engines. Bosch plugs are OEM for most Mercedes engines and it works very well.

The Bosch OEM plug of my 2000 E430 was replaced with Bosch at 80k miles and it looked like new.
 
Just ordered and received a set of Bosch plugs for my Volvo. Haven't installed them yet. But, when I looked at what was available, even from the dealer and a few Volvo sites, what they had were Denso with Volvo label( they are not the exact plug as factory). That is the way it is in USA when you have a european vehicle in so many cases. Went to Bosch site and could find the original factory plugs installed by car vin number. Entered the vin number and found the plugs you could never find at a parts place, and ordered them.

Replace with something else. NGK or Denso.
 
NGK or Denso only in that car. Bosch is junk for anything other than German cars.
 
Really? Running Bosch Iridium in my 2004 Nissan Maxima with no trouble. Can someone explain how, when all it does is make a spark, why they are 'junk' in all but German cars, or is it all anecdotal and butt meter reporting?
 
I can also add that I used a set of Bosch Iridiums in my Hyundai XG350 and the car didn't like them at all (strange idle,lack of power,lastly Misfire and CEL), changed them to NGK Iridium and it runs silky smooth again.

Lesson learned the back 3 plugs are a pain to get to, do it once, do it right, use NGK in a Hyundai.

Even German cars do not always use Bosch. I just did a set on a 330ci and the OE plugs were NGK.
 
LOL, I can't believe the myth that "German plugs can't be used in a Japanese engine" (and similar [censored]) is still flying around. If you are having problems with a Bosch plug in a Japanese car, you are using the wrong plug: heat range, gap, etc.

There are literally millions of German cars running around with Japanese plugs, and vice-versa.


But hey, your car, your money. If you feel better knowing that you have NGK plugs in a Toyota, more power to you.

I owned several SAABs, they all came with NGK from the factory. Apparently the Swedish guys didn't have the same knee jerk loyalty to Bosch that the Germans do. I've also seen more than my share of lousy Bosch switches, relays, and sensors, all sold at grand prices. I might add. Bosch has sold repackaged NGK O2 sensors for some time. I've been running NGK in my BMW bike for some time, in the suggested by NGK heat range, I'm very pleased.

Anecdotally, in the past 10 years or so I've had nothing but problems with the Bosch platinum plugs.

Tow escorts, a cavalier, and a VW sirocco all developed unexplained misfires well before the end of life for the plug (60k). All misfires and hard starts were resolved by new plugs, mostly NGK g-power.

The sirocco was the most dramatic change. The OEM plug from NGK were a non platinum side gapped plug whereas the Bosch platinum was a conventional plug and it ran like garbage since day 1 with the Bosch.

10 years ago Bosch platinum were my go to plug for everything. They always ran great. Somewhere in the mean time, something changed and they don't seem to hold up to the 60k (usually developing problems in the 30k range).

Since that time, the NGK G-Power is my go to plug where available.

The E3 plugs have shown some promise for me as well, so I might be giving them a whirl in some of the fleet as well.
 
I used all of the following plug brands (both conventional and platinum) in my Honda and could tell virtually no difference other than the fact that the metal part on the Autolite plugs rusted.

Champion (US built Honda, came with these OEM)
Denso
NGK
Bosch
Split Fire
E3
Autolite

I am not sure where all these plug myths originated.

The Bosch plugs for the aftermarket save for the Super and their new fine-wire "OEM" platinum/iridium plugs aren't the greatest. Even so, BMW, VW and Mercedes aren't as hard for Bosch anymore.

I'd still use Bosch conventionally-tipped or fine-wire Pt/Ir plugs with confidence.
 
Yep, a lot of people don't realize that Bosch and NGK had (have?) a licensing agreement.
