Lifted from a post on ToyotaNation.Does yours use the OEM twin ground platinum electrode spark plugs? They are specifically used for the later model Gen 4s (Camry) with twin coil packs and distributorless. These use a waste spark ignition, therefore the plugs fire twice during a 4 stroke cycle. If you use a single ground electrode, it will severely shorten the life of the plug. e.g. 6,000rpm on your Camry engine will be like running 12,000rpm on another car, since the plug fires twice as often. You can also try double platinum plugs, i.e. plugs with a platinum chip also on the ground electrode. What happens in waste spark ignition is that 1 coil pack fires 2 spark plugs simultaneously, e.g. cylinder 1 and cylinder 4. So while one spark plug is firing normally, spark jumps from center electrode to ground electrode, the other spark plug is firing in reverse, i.e. from ground electrode to center electrode, therefore there is high wear on the ground electrode, this is where the platinum chip on the ground electrode gives longevity. Plugs like Denso Iridium SK20R11 and VK20 also have a platinum chip on the ground electrode. NGK Iridium IX and Denso IK20 don't.
BOSCH R3 Platinum2 18-3770-8 spark plug is an alternative choice. Had replaced with these spark plugs for 2 years now, so far so good. By the way, the original stock Denso plugs were still very good after 100,000 miles (160,000kms). IMHO that they could go at least 200,000 miles before needing replacement.
what is the differences between public company and listed company
the public listed company any one can view their web site and as for the listed not every one can view their website
The gray wolf overall is listed as a species of least concern. However, a few subspecies are listed as threatened or endangered.
A listed investment is a closed-end investment, while a quoted investment has visible market valuation. In a listed investment the manager does not have to worry about funds being withdrawn.
In the United States alone, there are 496 animals listed on the endangered species list, and 735 plants listed on the endangered species list.
Just saw one listed for 75.00. Saw another listed for 1100.00. HUGE difference. I will keep looking
