As the title says - need spark plugs.
Ive read to get the NGK IK22 or the IK24.

Whats the difference and what do you guys recommend?

 

I recommend the OEM NGK's for a N/A car. If it isn't broke...

 

We recommend OEM NGK's IFR7G-11KS if you car is NA. We have them in stock. Give us a call when you're ready to order 949-457-1234 ext 2.

IK22 and IK24 are Denso not NGK. IK24 are good just more expensive. IK22 are OEM iridiums.

 

what the size needed for the spark plug removal?

im going to have buy this damned tool

 

NGK BKR7Es work perfectly too, even for boosted applications. They're less than $2 per plug and should be available at your local Auto Zone or Advance store.

 

Just go to a tool store and ask for a spark plug socket. There are only 2 sizes that are commonly used and Hondas use the smaller one (I am unsure of the size but I will update this post when I get home from work and look at it).

 

5/8" is the size. Get a reasonably good one like a Craftsman. I've read about people rounding off spark plugs and it would seriously suck to have to deal with that. I can't imagine how they are doing it but it probably starts with cheap tools.

It's a good idea to tape the socket to the extension because they tend to get stuck on the plugs.

 

stay away from denso plug, there's a few of those with broken tip and a broken motor because of it

cheap tool doesn't stripe off spark plug, people don't know how to use it properly does

 

The difference between the IK22 and IK24 is the heat range. The IK22 is the stock heat range, which is hotter than the IK24. When I had my '02 S2000, I switched to the IK24 because it was colder, and would be less likely to cause pre-detonation. I believe this was part of the reason why my '02 consistantly had slightly more advanced timing curves than my buddy's '02 S2000 when we datalogged via OBDII. The only downside to the IK24 was that if I did several really short drives in a row, the IK24's would sometimes get a little bit fouled. Whenever that happened, it would miss a little bit until I cleaned them up with about 5 miles of spirrited driving. When I say short drives, I mean really short drives, like 1 mile to the beer store and back during an ice storm.
