X5 3.0 spark plug replacement

[kenlee2003]

Another question that I have is for my BMW X5 2004 3.0 E53 Model (with only 65,000 miles) is that I have to change the connector boots with the spark plugs. I can't seem to find them. Do they make connector boots for my car? The dealer is telling me that they only sell Coils with the boots. I am assuming that I don't need to replace the boots when I replacing the spark plugs.

You dont need to replace the boots when replacing the plugs. Check with the forum vendors if you need them.

I don't think you can just replace the boot as it appears to be part of the coil pack. I didn't when I did mine nearly 3 years ago.

Autohaus offers NGK and Bosch

TIA

Either should be fine...just go with what you like. My '04 OE came with Bosch and I swapped them out with NGK...both performed the same on my butt dyno.

Sure enough that I didn't have to remove anything. I went out and bought a 6 inch extension. I followed everyone's suggestions. I have replaced all my spark plugs. Thank you.

Is a six inch extension needed?

I guess a 6' inch is fine. I used a swivel spark plug socket. Helped a lot.

I think I used a 6" extension. You only really need it for the back 2 spark plugs. Just enough to get down deep enough to get on the plug, but not too tall that you can't get the extension/socket in the hole and/or be able to remove the plug when unscrewed

Got in there with the 6 inch extension. Tight though... but done
