Product Review

If you're looking for the very latest in spark plug technology, look no further than Bosch Platinum Ir Fusion. Fusion features a patented, fused iridium and platinum center electrode, combined with exclusive surface air gap firing technology to produce a longer, more powerful spark. Its four yttrium-enhanced ground electrode design outperforms OE iridium plugs by significantly reducing gap wear. This means less stress on the ignition system for quicker starts, more efficient fuel combustion, and a longer performance life. In addition, Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system.

This review is from: Bosch (4507) WGR9DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
I used these in a 1996 Dodge Grand Caravan and have had no problems whatsoever. The sparkplugs are really hard to get to in a lot of minivans, and I didn't want to do the job again anytime soon. I probably could have made due with the dual platinum plugs the van came with, but these seem to be working just as good and I don't think I'll have to change them again.

I put these plugs into a 2002 Ford Windstar and was impressed with the increase in acceleration and engine smoothness.

This spark plug is made very good. I replaced the denso standard plug with the bosh platinum ir fusion. I have noticed a difference in starting and a little in power. The standard denso's were not bad but the bosh were on sale so I thought I would give them a try. No plug is going to be a magic power plug but any difference is worth it. I will have to wait to see if it changes gas mileage. Even if they don't increase mileage it is still worth the change to me because they will last longer. They have four prongs to take the wear and heat. I remember the Rotary engine had to have four prongs for high spark and heat. So even though the tacoma does'nt have a high volt system it will help in the wear. Again to me so far it has helped; starts faster, runs even smoother through rpm range. As with any product only time will tell. Spark plugs have been the same for many years it is time for a change in design. Is four prongs the new answer to better plugs? Try them while they are on sale and...Read more
