Ive had great success with the new Bosch Iridium fusion plugs. They fire well and I've not lost any fuel economy or power with them. I got the model 4501 and replaced them at 30K. I plan on replacing them again at 100K since they're long lasting plugs.

$40 for once every 50-70k miles is pretty good investment. Try a serach, there are a few threads with plug discussions.

I did the same thing yesterday. Instead I of the factory numbered NGK's I got the NGK G power. I think they were $2something a plug. Everything is running fine so far. I've only put 20miles on it since I changed them. Anything would be better in my car, when I pulled the plugs they ranged from 37-49 on the plug gaps! Factory is 39.

Brisk are nice plugs but usually very expensive and not necessarily a long lasting plug. you lose some durability for the higher performance. usually these plugs are used where high rpm and high coil voltage is needed, because the coil has a short time to "recharge" between firings the faster the engine speed, so these minimize the voltage drop across the plug itself, to make up for some loss in the coil. I have seen some Brisk plugs that were almost $50 each.. and perrin doesnt cut any corners when it comes to pricing.

Same deal with mine. The old ones were way out of factory gap, between 44 and about 50 on all 4 of them. Put the new gap on my NGK standards down to 32 and haven't noticed any ill effects 8,000 miles later. I've yet to check how they're wearing, but throttle response immediately after changing them was like going from night to day.

I ran them for almost a year before they started breaking down. Not worth the money IMHO.
