I have now 54-55k miles on my mcs and think its about time to change the spark plugs.

Plus I think one is bad due to start up and check engine light coming on randomly then turning off. I haven't had time to get the code -_-

But hey it wouldn't hurt to change it and see if it helps the problem or not

Anyone recommend a good brand? Where to get it at a store or online?

Thanks.

ngk laser iridiums?

 

Can i get them at autozone?

What about the Pulstar sparkplug.

 

I've just installed the Pulstar plugs in my MINI. After running with the originals for 90k it's certainly made a difference.

 

Sooo for the extra money its worth it?

Do you notice better start up? fuel economy?

 

For as long as the R56 has been out, most tuner shops haven't really recommended any new spectacular plug. It might be best to stick with the stock plug...

NGK ILZKBR7A-8G

 

Stay Stock unless your mods list grows and you require upgraded plugs.

After 55K on those plugs you will notice a different feel as soon as you replace those plugs with anything even stock.
I would recommend staying stock for now. IMO

 

Have tried to find a colder ngk for the turbo motor and all that is offered is a copper plug

 

copper plugs are good, my teacher runs autolite $3.88 copper plugs on his 1500hp turbo mustang

 

I have thought about changing my plugs also, recently found out Brisk makes a silver plug for the R56. I believe Alta is selling them. I believe they were a good plug in the R53 but don't know anyone with them in an R56. Any oppinions?

 

If you are not running into pre-ignition issues, the only thing you will gain with a colder plug is poor start up behavior and poor gas mileage until the car is warm.

 

Too true. High hp motors like that tend to get a spark plug change quite often so running rediculously expensive plugs makes little sense at all.

 

Does it matter if I just get better plugs now then later? Will it effect my engine?

 

Doesnt Way Motor Works sell a set of Iridiums with a colder heat range?

bought my new NGK ILZKBR7A-8G plugs at AutoZone. got 46,500 miles when i changed them, def needed them! smoother running.

 

Denso= Made by Toyota crap

 

DENSO....BAD!!!!!

 

Just some more spark plug information for others about to do it... NGK ILZKBR7A8G is part number 5992. Autozone by me (NY) cannot order these anymore, but listed them for $15.99. Local auto shops could buy them, but the cost was $25/plug (the same cost as my local MINI dealership - Prestige). I found the plugs on Amazon for $15.xx, which is tax free/shipping free (prime members). Hope that helps...

 

I just found the same NGK plug for $12.98 at rockauto.com

cool i just ordered a set from rockauto. thanks slinger688

 

anybody know where to get the 12 sided socket for the plugs?

 

and what are the torque specs as well? 25 ft lbs?

 

I ran copper plugs in my VR6 turbo car. They work awesome you just have to change them around every oil change (4K). They're cheap as heck, too.

 

You can get the socket at Sears (craftsman). I think it was about $6-7. NOTE: I had to grind the outside of mine down because as I unscrewed the spark plugs the socket got warm and expanded and got stuck. There was very little clearance between the sidewall and the socket. The socket is thick, so I just rolled it against my grinding wheel.

 

I picked mine up from Sears. You don't really need to buy the special socket. I use a regular 12 point 14mm socket and stick a small piece of bubble wrap in it to hold the plug in place. It works great.

I have done the plugs twice now and no problem with the socket getting stuck. The torque spec is on the box if you get them from the dealer. I believe the spark plug is torque is around 23 newton meters but DEFINITELY NOT 25 FOOT POUNDS.
