5.0 out of 5 stars Spark plugs are hot, October 4, 2007

By	G. Varga - See all my reviews (REAL NAME)

This review is from: Bosch (4503) FGR7DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)

I bought a set of six for my three series and they are exactly as represented. Top of the line plugs from Bosch. Installed and car runs perfectly.
I'll tell you more after the next 100,000 miles with them!

5.0 out of 5 stars Better mileage, November 21, 2009

By	T. Guggisberg - See all my reviews (REAL NAME)

This review is from: Bosch (4503) FGR7DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)

I tried these plugs on my 2004 Honda Accord to see if they make a difference. The car only has 50k miles, well below the factory recommended change interval for the spark plugs. My average mileage has increased from about 26 to 28.5 MPG. They'll pay for themselves quickly with today's gas prices.

5.0 out of 5 stars Great plugs, November 8, 2009

By	ZZM "4Dkhawk" (Chicago, IL USA) - See all my reviews

Amazon Verified Purchase(What's this?)

This review is from: Bosch (4503) FGR7DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)

Excellent spark plugs, I noticed the difference of the engine noise right away, especially when driving above 45Mph , the engine runs much smoother and quieter.It appears that 4 prongs does make a big difference over 1 prong, the car accelerates smoother and faster as well.It cost five times more than a cheap 99cent plug (after rebate) but its worth it.
Highly recommended.

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. Read more
