Hi,

The dealer wants $18 for 1 spark plug, and another $18 for a bottle of coolant.

I don't mind to pay that much but I feel like they want to rip me off. Is it really this much for the spark plug and the coolant?

 

You're being ripped off. Acura doesn't manufacture the spark plug themselves. The spark plugs in your car are NGK IZFR6K-11. Get them at any auto parts store. To be 110% sure, just pull out a plug and check the part number on it.

How big is that bottle of coolant? I hope it is at least 1 gallon. You can use Honda Type-II coolant as well. Both of them are the same. But don't use any other aftermarket coolant.

 

We use Denso Iridium spark plugs. On the Denso website, they have them for under $12 per plug. http://www.densoproducts.com/results...ctCategoryID=1

 

According to this link we use either Denso or NGK.

Which is better?

You can use either. I like NGK because it's easily available here.

 

Thanks guys.

I was kinda of ok when the guy told me $18 for the spark plug after all the guy got to make a living working there... BUT NOT until he told me $18 EACH. I was shocked for 10 seconds standing in front of the counter making a fool out of myself...

How much should a bottle of coolant in the Honda dealer instead of the Acura dealer do you know?

 

I don't get it.

I went to Kragen. The guy punched in the part number and it popped out 2 items. One was $21 dollars. The other one was $10 bucks.

Both were NGK IZFR6K-11.

What is the different?

The Kragen part# is #6994

any idea?

 

Is there an advantage to getting a "hotter" or "colder" plug if your car only has basic bolt-ons and Hondata reflash?

 

Here in Australia, they cost US$17 each. So it must be less than that in the US since everything is cheaper there. They are expensive because they are iridium plugs. If you go for copper plugs, they are less than $3 each. But why go copper when your engine can run clean enough to use iridiums and you won't have to replace your plugs for the next 75,000km.

Not sure about coolant prices there, here we pay US$34 for 5L from Honda.

Have a look at both parts. If they are the same, go for the cheaper one (remember to ask for the price for 4 pieces. )

 

If you use a plug colder than specced, then it doesn't get hot enough to burn off the deposits that get on the plug during normal use. If you use a plug hotter than specced, then you get preignition (i.e. pinging).

Hotter and colder are not the rating of the spark temperature. They are the measure of how well the spark plug body conducts heat away from the electrode. So choose a plug suitable for your setup because it is what your engine needs. You don't choose it based on any advantages.

 

screw the big box part store.

I went to a R-E-A-L auto part store and got the plug EXACTLY the same as the one from the NGK website for $11 each out the door... no tax.. no shipping... no handling.. no waiting... what-so-ever... but only with a little insult by the guy over there who told me that my souped up 4 banger Accord didn't need this kind of expensive parts... hahahaha!!!


I will change the plugs this weekend.

Just noticed a typo in my post above. Iridiums last 75000 MILES, not km.

 

The NGK website doesn't say how long the spark plug will last. It only says it depends on the type of engine, and it should be consulted with a "trusted" mechanic...

Hmmm... the part that says "trusted" make me wonder...

Last time I took my car to the dealership to change oil, the guy either didn't fully drain the oil or he didn't event change the oil at all... and then he pumped 4+ quarts oil to my car over filling it.

When I got home, I checked the oil level and I knew it was a mess. I tried to drain out some oil but the drain plug was w-a-y over tied!!! And guess what... the oil I let out was dark! not flash at all!!!

Look at the chart.

 

Hi guy. I've replaced the spark plugs. This is the different between the 2-dollar plug from the 20-dollar plug. The tip looks virtually brand new and clean after 110k+ miles.

 

Your plug looks good with just deposits and that very worn electrode.

 

I would put some anti-seize on the new plugs before installing.

 

The spot where the actual spark strike look very shiny on the inside of the electrode...

I was going to clean the old plugs and put them back... but if it said change the plugs at 110k... So... just change it right?

 

My mechanic told me not to use any anti-seize compound. He said the grease could pick up some dirt (big and small). When I was going to put the plug back, the dirt could go mess up the thread. So, he said it was better not to use it.

He also told me not to use any tune up grease. He said it didn't do anything for those with the coil placed directly to the plug.

 

Unless you are installing the plugs outside during the middle of a desert storm, it's not likely dirt will get on the thread and causes problem. OTOH, the threads in the aluminum cylinder head could be ruined by lack of anti-seize and exposing to high heat. It's your engine, so it's up to you...

 

 

But if you have already installed the plugs, leave them be because the crush washer won't be too happy to be crushed twice.

 

I do not worry about it. By the time I need to replace the spark plugs again, it will be 200k+ miles... (if the car can last 200+ at all)

 

The difference is NOTHING! I spoke with a guy at Advance Auto Parts today. IZFR6K-11 is the OEM replacement model number. 6994 is the same plug, but with a regular NGK part number.

What a scam to screw people who are searching/buying based on the OEM part #

 

Do you need a bottle of coolant For when u change sparks plugs?
