Car Forum / Honda Cars / December 2005Bosch Spark Plug (Platinum +4)
Hi, My friend just called and asked me what plugs should he get for his 2002 Civic Lx (5 Speed). He seems to be very inclined for Bosch Spark Plugs (Platinum +4). I am not very knowledgeable person in cars but keep reading this group. And he knows that :) Any suggestions for this Platinum +4 plugs please. http://aa.bosch.de/advastaboschaa/Product.jsp?prod_id=76&ccat_id=26&language=en- GB&publication=1 http://www.boschusa.com/AutoParts/SparkPlugs/PlatinumPlus4/ Thank you. > Hi, > [quoted text clipped - 11 lines] > > Thank you.

There is a body of anecdotal evidence that says that Bosch plugs don't work well in Hondas. Since I've never used Bosch, I can't say one way or the other.

I'm not familiar with how good they are these days, but they used to be crap. High performance motorcycle engines ate them like candy and the best thing you could do was replace them with ...anything. Since I'm no longer a m/c wrench, I'm not up on their current reliability, but do realize they may have improved. nb >> There is a body of anecdotal evidence that says that Bosch plugs >> don't work well in Hondas.

It might be one of those things like the FRAM oil filter evidence, which I'm personally skeptical about. > I use Bosch Platinum2's in my Honda and my Harley. The > suckers last forever.

High performance > motorcycle engines ate them like candy NGK platinums wear from a .043" gap to .050" in 30K miles in my B18A1. Mind you it also spends about 75% of its drive time at 4,000 rpm or more. Life was improved once I moved down one heat range.

When I replaced them with the recommended NGKs ($12 each!), it ran much better.

I had something called "Splitfires" for a while in my 'Teg years ago, and experienced the same thing. Replacement with NGKs made the rough idle go away. I don't see how the two are really related, and I don't know if the symptom was psychosomatic, but that's what I felt at the time.

The +2s have been working great in my '87 Accord for several months now. I can't say they're significantly better or worse than any others, because they replaced some fairly dirty Motomaster (Canadian Tire brand) plugs and I haven't done any kind of comparison testing other than empirical comparison to a variety of "standard" type plugs used on my previous two Accords... but they haven't showed any signs of fouling so far and seem to be working as well now as when I put them in. But that's just anecdotal evidence as well - YMMV (no pun intended). --- avast! Antivirus: Outbound message clean.

My 99 Prelude Service Manual only lists NGK and Denso plugs, but my 84 Prelude manual (I'm a pack rat) lists NGK: BPR6EY-11 and ND: W20EXR-U11. Although I no longer have the 90 manual, I seem to recall NGK and ND.

Listing them and recommending them are two different things. If they were to list every brand and model of plug that would work, it would probably take several pages, and probably become more inaccurate over time as brands come and go. Listing the ones they THEY supply in the car seems a reasonable assumption, without necessarily saying they "recommend" them (unless they DO use the word "recommend" in your manual - AFAICR they don't in my '87 Accord manual). --- avast!

OK, the 84 Service Manual listed only the NGK and ND part numbers in both the Maintenance Schedule and in the Engine section, without stating "Recommended" or otherwise. Any reasonable person would assume that IS a recommendation since that's what Honda was supplying. However, my 99 manual flat out states, "NOTE: Use only the spark plugs listed below:", (one NGK and one Denso - both are platinum). Again, this is what Honda supplied and I interpret this to also mean "Recommended". J, He ended up buying platinum +4 plugs and so far he is happy. Lets see how it goes in long run. Bosch plugs seem to loosen. Had two do that in my BMW--one totally popped out. (Should probably check the other two.) And I always use a torque wrench and anti-seize. |
