Comment: 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.

Summary: Good plugs 2010-03-22
Comment: 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.

Summary: Inflated MSRP. BEWARE 2010-02-09
Comment: 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!
