I've got no personal experience with these particular plugs. My overall
experience with Bosch plugs is positive.

Waste of money. The four electrodes are nothing but a gimmick.

Well, it's either due to the placebo effect or their plugs were really
bad and putting in new ones restored the performance they had lost. ANY
new plug would do that.

I agree with Hyundaitech that NGK and Nippon Denso are excellent plugs.

You still only get one spark on most OEM ignition systems. They're
pretty awesome if you've got a high voltage/current multi-spark ignition
system like an MSD from what I hear.. If you don't have this, the
additional electrodes just block fuel/air flow around the ignition area,
which is a Very Bad Thing (tm).

I tried the Bosch single platinums in my Santa Fe.. I noticed a severe
fuel economy/power loss with regular misfires. Checked to make sure all
the connections were tight - they were... Replaced the plugs and the
problem went away, go figure.

Spark plugs are cheap and easy to swap out, and unless you buy the wrong
length (look it up and double check visually before installation),
seal-type (wedge or washer) or heat range (not every parts store
computer is correct - always check against the plug manufacturer's
application sheet, these can always be found online)

Best plugs I've found so far for the 2.7 are the Champion Truck Plugs.
They're copper so its easy on the ignition electronics, but last as long
as most platinums (I'm at about 55k on these plugs so far on the 01,
still have the same gap, no misfires, no typical champion 'blow-by'
around the ceramic, and no noticable drop in fuel economy)

If you're into the cheezy OEM wire sets arcing-out and blown coil packs,
stick to using the platinum plugs. Otherwise, look for a good copper plug.

Exactly. The same is true of the 2 and 3 electrode plugs on the market.
If your car has multi-spark ignition, you don't need multi electrode
plugs, so there's still no benefit to them.

I've heard of reports of problems with Bosch plugs in Elantras as well.
I don't think it's a quality issue, as they're well made, but perhasp
they got the heat range wrong or something.

Interesting. I'd never heard of them.

Like the NGK V-power plugs. The part number for the Elantra is BKR5E-11.
Their standard copper plugs are #BKR5ES-11.

I bought 6 plugs at the dealer at $13 each at 60,000 miles, and put them in
my 2002 XG350. A week later I find that a suitable equilivent plug (still
platinum) is available for around $2.00 each at the auto parts store. I
bought a set and repalaced the front three (the easy three) and have been
driving that way for almost 30,000 miles now. I can't tell the difference.
I won't know for another 30,000 how they look compared to the expensive
ones, but I suspect they will look about the same. Check out your local
auto store before spending $80 on a set of plugs.
