5.0 out of 5 stars Sparks Plugs, September 22, 2009

This review is from: Bosch (4512) FGR9DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
These spark plugs are great...really good acceleration. But I don't see any mileage improvements.

5.0 out of 5 stars Good plugs, March 21, 2010
Amazon Verified Purchase(What's this?)
This review is from: Bosch (4512) FGR9DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
I bought these plugs for my 2007 Sonata 4 cylinder. What the other reviewer said is only partially right about the cost. Amazon's listed 'original' price is a bit absurd. However, the sale price is better than any other place online or in store. The rebate applies to all new purchases including Amazon. At the current price after rebate, they cost me about 15 bucks total. My old plugs were not too bad; but I still feel better acceleration (very slight) and slightly better mpg. I can get about 30mpg mixed versus the old 28-29mpg mixed. I have yet to do a full highway tank yet (with traffic... that's rare) but I used to get 34.... wonder if I can break 35 now. Overall great plugs for my car. At $15 total... it'll pay for itself in no time in mpg savings.

This review is from: Bosch (4512) FGR9DQI Platinum IR Fusion Spark Plug, Pack of 1 (Misc.)
Am very happy with these long lasting plugs, but as with all such one really needs to put anti-seize compound on the threads so they don't lock in.

1.0 out of 5 stars Inflated MSRP. BEWARE
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
