I recommend you be prepared to do the infamous coolant pipes while dismantling, if they have not been done. I have never tried one of those scopes to try and peak under/past the intake manifold, but think it would work. If the pipes are black....they are plastic. If silver they have been done.

If you are thinking you need to do the pipes and DONT plan to do the job yourself, hand your spark plugs to the guy doing the pipes and have him do it while all the "stuff" is out of the way.

If you are not familiar with the bogus coolant pipe issue, read the sticky on this forum or google "Ceyenne coolant pipe failure"

 

I did research the coolant pipes before buying, i just want to make sure i use the right plugs, are bosch or beru better? ngk?

 

Beru is the OEM plug - therefore it's tried and true with predictable results.

NGK or Bosch will work if they're the correct plug application. It's highly unlikely you'd ever notice the difference between any of them. You could save a hundred bucks with some cheaper versions from NGK, but I believe they wear out in 20K miles.

If you want to install plugs without worrying about gap, longevity, etc - get Beru. If you want to save 40 bucks - go with something else. There isn't a "best" plug for the Cayenne. For me - I don't like problems, and 40 bucks is a drop in the bucket compared to the 3 grand I spend annually on gas.

It takes some time to do the plugs because the beauty covers need to come off. But, it's not hard.

 

OEM is a better choice. Try Suncoast. The might have the best prices.

 

I grabbed this set from ECS for $50.

If you're doing the plugs you might as well do the ignition coils too while you're in there.
