I went to Autozone to pick up some spark plugs for my 2002 Land Rover Discovery II SE and found that I had two engine types to choose from:

8 Cylinders 2 4.0L MFI OHV

or

8 Cylinders 5 4.0L MFI

and I had no idea which mine was. I went with the first one (OHV) and got some NGK platinum plugs.

Did I get the right ones or not? I need to know because I'm going to have them installed tomorrow morning. How do I find out which engine my Discovery is?

Thanks.

Your 2 engines are a LEV and non LEV.
If you have the engine in the link above then you have the LEV engine.

I think I do have the one mentioned above. Here are two pictures from each side of my engine:

 

Hey wizdom...just an observation...those look like the original OEM wires in your pics...as long as you are replacing the plugs (if it were me), I would also replace the wires with Magnecor, STI or Kingsborne 8mm...if they are original, it is about time to replace.

 

Yep, I bought the parts already. Got a new ignition coil (it was acting up), 8mm Kingsborne, and NGK platinum plugs

 

Yes you have SAI (secondary air injection), thats what those round thingy's are, air pumps to force fresh air into your exhaust to help the catalytic converters get to temp faster.
Think of them as a blacksmiths bellows.

 

How do you know your coil was acting up, what fault code numbers did you get? I wouldn't install it on just a guess, kinda of a waste of money.

 

Well the mechanic told me it was acting up. I wasn't completely convinced. Nevertheless, I bought all the parts and he installed them yesterday. Everything seems to be working fine now.

I don't remember the exact codes. In retrospect, I should have written them down.
