I've been using Denso Iridium on my A/T car for almost 20k km now. No problems at all.

For street use, I'd recommend sticking with the recommended spark plugs listed in the owner's manual. The manual usually gives you the specific plug brands and part numbers they recommend for your engine. Just choose from the list which one is available in your area.

I normally use the ordinary spark plug. NGK or Denso

The NGK iridium would be nice lalo na for Honda and Nissan rice car.

Pro seriously, NGK is by far the best quality spark plug in the industry. Notice how many fresh casa cars uses NGK.

for me, i just use the stock NGK plugs, and regularly replace it every 10,000 kms.

Use the stock spark plug. If you want a little more out of your plugs, use the iridium or platinum version of the stock plug.

Combustion chamber design is a dark art, and the stock plugs are chosen specifically for their heat range, height and placement within the chamber. Buying longer tips, shorter tips, multiple tip (four tip Bosch or dual tip Splitfires) or whatever plugs will change the combustion characteristics, often for the worse.

Sometimes you get lucky, sometimes you don't. You can get more performance out of your car by properly "gapping" the stock plugs to ensure a cleaner spark. ;)

Pero marami na ring naglabasang fake [SIZE=3]NGK[/SIZE] sparkplugs nowadays. NGK din ako nuon, pero nang mabiktima ng peke ay nag- [SIZE=3]Denso[/SIZE] na ako for my Honda and Nissan. So far e OK naman.

IMHO, the Bosch 4-tip version sucks!
