This is one thing that Acura did right. The factory NGK Iridium IZFR6K11 plugs are a great plug for the TL. They are costly but well worth the money. And they can last up to 105,000 miles, so depending on your mileage, you may not even need to change them just yet, but that's your decision. I replaced mine at 88,000 miles right before I replaced the timing belt and waterpump.

I would stick with stock unless you go to F/I then I went with the Denso IK22 that Comptech swears by.

I've got to start copying and storing these posts somewhere, I think I've posted the exact same thing a hundred times.
Go with factory and you can be assured you will have no issues for a very long time. You can't go wrong with factory.
With that said, there's nothing wrong with platinum and even regular old $2 plugs if you shorten the change interval. All of those plugs will start out with the same performance. Iridiums will outlast the rest. If you don't mind changing the plugs every 40K or so, run regular old plugs. I've had this batch in for a little over 40K, getting ready to change again and it will cost me less than $15.
Again, you can't go wrong with factory but there are other valid options if you change more often. I enjoy changing the plugs and it gives you a chance to see what's going on in the combustion chamber. You can see if you have a lean or rich cylinder, you can tell if compression is getting low, you can see if there's been any severe detonation, etc. It's not for everyone but I thought I would throw it out there.

These actually aren't that expensive. Theres a set on ebay, 6 for 57.50 with free shipping.

I just bought a set of 3g's for my '07 tl-S and a tech at the dealer told me not to put them in as it will alter the burn rate in the motor. Need a real tech to confirm or deny. He said, leave the stockers in.

The burn rate is determined by the gasoline used.
However, these plugs are regular plain copper. Why is it that people discourage using plain copper plugs yet when they come with fancy advertising (false advertising) and useless additional electrodes which shroud the spark resulting in worse mpg and power people jump all over them?

Plugs might help a little. I would try a couple rounds of Seafoam.

the factory plugs are really good and they can last 100K miles without much of an issue. I bought the same ones from Autozone for around 60 dollars for all 6. They had a coupon online where if you buy over 50 dollars worth of stuff they give you 15 dollars off so it makes everything a bit cheaper!

I don't want to be negative but don't get your hopes up. Unless you have a misfire caused from the plugs (which you don't), you would be lucky to notice a VERY minimal difference which would most likely show up as a slightly better cold idle.

It may help to use a fuel cleaner to get rid of any carbon build-up and the other gunk that may be in your fuel lines, injectors, etc.
