Under $60 shipped on eBay. Don't think O'reilly can beat that.

get the bosch plugs out ASAP- they are the wrong plug and dont work very long before having issues
At least now you can still get a refund for them selling you those pieces of....
The car is labeled NGK or Denso, so why would you buy a german plug for a japanese car?

Hey where did you pull that cool table out of? I've been trying to find some how to's on routine maintenance,i.e. changing plugs, but i have no luck. I've only owned american cars, and this might be a bit more tricky. It's good to have a guide to go by.

I think the Bosch will work just fine. But no doubt NGKs will last a lot longer and are more reliable. My buddy put some bosch like yours in his civic he raced. About 2k later, the tips on bosch melted. No doubt NGKs are the way to go. Auto zone got em for 10 bucks a piece. Not bad considering they are 100k plugs.

and as basically just said the tips go/wear real fast, which is't too good for producing a GOOD spark to ignite the air fuel mixture
so kinda pointless when you gotta replace them in 2k miles

One thing you guys need to realize is the iridiums are only there so Acura can sell the car with the "105,000 mile" first tune up. They're great plugs but not necessary as so many people believe. I pulled the factory plugs around 40,000 and replaced them with platinums one heat range colder. Now that it's turned 85,000 miles I'll probably replace them with regular old traditional plugs. The reason is I change them every 40,000 miles so iridiums are a waste of money for me. It's cheaper to replace normal plugs every 40K and get a picture of what's going on inside of the combustion chamber than iridiums every 105,000 miles. It's also not fun pulling plugs that have been stuck in the head for over 100,000 miles.
If you plan on going another 100K, by all means use iridiums.
As for others wearing out super fast because they're not iridiums, I will promise you it's due to a defect in the plugs. If regular plugs work in my GN with 29psi boost and over 100hp per cylinder, they're not going to have a problem in the TL.
The only real problems are the "gimmick" plugs. Stay with a normal single electrode non-multiple spark spark plug and you're going to be fine as long as you follow the recommended change interval.

anyways stock replacements work good for me
, but i will proably replace them again at another 90K (so 180K total on the car) though, geneally wasted by then anyways (if i don't replace them before then though with colder plugs, for the power adders)some of it is lazyiness for doing them though, and so wanting them to last
also about the multiple electrodes, check out alot of stock toyota plugs, they come with twin electrodes from the factory, but they are also DENSO plugs at least, and not some gimmicky ones

Labor cost on replacing plugs sucks. Due to lack of time, and just being flat out too lazy, I had the dealership do my plugs. 1.5hrs of labor and $250 later (oil change included) and I'm on my fresh plugs. I think it was the first time they've been done in 66k miles. 
. What was the brand and model? Maybe a part number

The OEM PLUG, If Acura had a better plug they would put it in from the facory. Maybe some of these people are smarter than engineers at Honda. I forgot that Honda is a public traded company with millions at there disposal for R&D. Just a thought!

Engineers have a set of goals. One is a super long change interval as a selling point of the car. Iridium meets this goal.
However, plain old copper meets any performance goal that iridium and platinum can meet. It just won't last as long.
As for the cooler plugs, the engineers obviously weren't on top of the pinging problem, now were they? And once again a hot plug will not foul out as easily as a cooler plug. The tradeoff is it's more detonation prone.
Inaccurate, I'll get that number for you when I get off of work. They've severely limited internet use due to a few bad seeds looking at things you would not expect them to look at at work. Amazing.....
On NGK's website it breaks down the part numbers. I believe higher is colder but I would have to double check. They do make a colder iridium now too.

Here's a link to NGK's page. I thought you would like the idea of a cooler plug. The only disadvantage is cooler plugs can foul out easier. But you have to figure the TL runs a fairly hot plug to pull off 105,000 mile intervals. I've seen no ill effects from one heat range cooler in the TL. In the other car I run 3 steps colder with no fouling problems. No performance loss and there's the potential for performance gain if they reduce detonation tendencies. Here's the link:

Well, against the advice of this board I just replaced the plugs in my 05 TL with Bosch Platinum IR Fusion (4501) plugs. Bought 6 off of amazon for $34.50 and am just about to mail in their $4 per plug rebate which means I will have got the plugs for $10.50.
Fitted then myself and must say the job went pretty well. I had to use a telescopic antenna with a magnet on the end to retrieve the plugs as my spark plug sockets rubber wasnt picking up the plugs.
Oh and the TL has 125k miles and I do about 2.5k miles a month. I hope the Bosch's will hold up as well as the original NGKs, we shall see.
