Honda Car Forum

I just installed the new Bosch Platinum plugs for my Civic 1.5 LX. (4
cyl)

Back in the days I used to own a 93 Infiniti Q45, and with that car you
had to install Platinum plugs. So, I thought why not replace my cheap
ass delco sparks as they were old and needed replacement with the
plats, should I feel much of a different between the two?

I know Platinum plugs are much better, but honestly how much more of a
difference could it possibly even make? maybe burn the fuel better,
quicker or something like that? I am not sure.

Thanks,
Janos

They are supposed to last longer, 100000kms or so. Hondas don't really like
Bosch plugs though, better to stick to NGK (they came from the factory with
these). Bosch plugs run alot hotter, and are more suited to euro imports...

Well, would it be safe to keep them in? I paid like $28 (7 each)
dollars for them, and hate wasting money. They are the Bosch Platinum
+4 Spark Plugs.

If your old plugs were in good usable condition, you should not expect
any difference upon installation of new Bosch Platinums.

The amount of hype and BS advertised about spark plugs is mind numbing.

Yet another urban legend, sigh.

it would probably be ok to keep them but you have four electrodes in each
cylinder now instead of 1...I would not want one of those things busting off
in my cylinder..

Platinums are Ok and I have used them for years in every vehicle I have
owned, including my current Honda, without problems. They will last longer
than the NGK without a doubt.

I don't think it's an urban legend - at least not about Bosch
platinums.
Their aftermarket platinum plugs feature a thin platinum wire buried
flush against the end of the insulator. There's no "heat range" per
se to them. My mechanic has nothing but bad things to say about
using them in Japanese makes. They had unusual failures where the
center electrode just vaporized away. Just look at the picture:

There's some inklings that the factory OEM platinum plugs by Bosch
are more of the traditional platinum fused to nickel alloy design.

Personally I think only NGK or Denso should ever go into a Honda.

I used Bosch platinums in a turbo Volvo (1985) and that very thing happened
within a year or so. No electrode left.

Bosch claims that the pure platinum wire will resist erosion. However,
it's a tiny tip (maybe .2 mm) and the only path for heat to travel out
of the center electrode. A typical platinum plug has a 2 mm wide
nickel alloy tip to transfer heat to the core.

I also had bad results with Bosch Platinums in a first generation VW
Passat in the early 1990s. I don't think the issues are
Japanese/European vehicle correlated at all.
