How to change spark plugs on 05 nissan pathy 4.0, V6?

It looks like the intake manifold will have to be removed.My question is does it have a gasket and is it reusable or will the gasket have to be replaced?How to change spark plugs on 05 nissan pathy 4.0, V6?
That is funny I remove the 6 coils and change the spark plugs with out removing the intake upper plenium. Yes it looks difficult but remember those platinum plugs last over 100,000 miles. Be sure to only use the spark plug brand and heat range that came with the truck. Changing the resistor value with the wrong plugs can cause other problems.
