Bosch has caused a lot of Japanese cars I know of personally to fail smog here in So. Cal. when equipped with Bosch parts, So I do not use Bosch parts in Japanese cars. I only use Denso or NGK. Also, having more than one ground electrode is useless since electricity follows the path of least resistance, those 3 extra ground electrodes are just a marketing gimmick.

most helpful post in here. = thank you.
and finally, someone else agrees with me on that 4 electrode BS!

I changed my plugs yesterday. My car is an XB 2006 w 25000 miles on it.

I went with Bosch +2 - $4.99 each at Autozone. Tell you the car seems to have a little more pep to it. Also put in a new pcv valve.

Easy as pie to put new plugs in. And yes, I used anti-seize lube on the threads.

Gonna take a raod trip soon so I tell you if the mileage changes in either direction. Been getting about 27 or so.
