You won't need to change the gap. When you buy spark plugs for most modern cars the plugs are usually preset to the correct gap. It is usually only adjusted if you are changing the performance level of the car.
A timing belt can last 50,000 miles or the life of the vehicle. In all honesty, you just never know. It all depends how the belt looks. If it is wore or missing teeth, then it would need changed. But, without seeing it, I would recommend changing it at 100,000 miles. They almost always last longer then that.
You should find another dealer. Hyundai recommends replacing the belt every 60,000 miles and this dealer knows this. No reason at all to replace it at 42,093 miles. Remember that this is an interference engine so if the belt breaks serious engine damage will occur. Do not neglect this service at 60,000 miles.
Your vehicle is equipped with a timing chain. There is no periodic maintenance schedule fr the timing chain.
If your spark plugs have never been changed, now might be a perfect opportunity to change them. Ensure that you properly gap the plugs before installation. You will find gap specs on the engine information tag/sticker under the hood.
You are correct. The plugs are accessed below these coils. Disconnect the coil connectors and remove the 4 10mm bolts which hold the coils in place -- then you'll have access to the plugs. Here's a pic
By the way, how many miles on this 2007 Sonata? You know the powertrain is under warranty (1st owner 100,000 miles). If you're having problems, have Hyundai dealership diagnose it and fix it under warranty.
Autozone will tell you the gap when you purchase the plugs.
Any plug will be fine. Wires are generally the same. pick the mid-priced pair for durability only. Better workmanship provides better wear and tear from the climate and temp. changes under the hood. Bosch is good quality and decently priced.
