1.0 out of 5 stars inflated MSRP. BEWARE, February 8, 2010
By David Popp (Nashville, TN) - See all my reviews

This review is from: Bosch (4507) WGR9DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
You can find a better deal somewhere else for these plugs. Amazon claims they are 89% off. You would think you're getting a pack of 4 plugs for a deal like that. This is not true. You only get 1 spark plug. Name one bosch plug that has a retail of over $52? I have found other issues where Amazon shows a bogus MSRP for items. DO NOT BUY THESE!

5.0 out of 5 stars seems to work fine, February 3, 2010

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.

By Jeffrey Johnson (Benton Harbor, MI) - See all my reviews
(REAL NAME)   
This review is from: Bosch (4507) WGR9DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
I put these plugs into a 2002 Ford Windstar and was impressed with the increase in acceleration and engine smoothness.
