I was wondering if anyone knew what it takes to replace the front three spark plugs. The back three were a piece of cake. The intake seems to be in the way. Please help not much hair left......

Welcome to the forum...
I know on some transverse engines is necessary to remove a motor mount and tilt the engine to gain access...
What year is your vehicle? engine size?

Information I have....Yes you have to remove the intake

Spark Plug Replacement
Removal Procedure
1. Remove the ignition coil(s). Refer to Ignition Coil Replacement - Bank 1 and/or Ignition Coil
Replacement - Bank 2.
Warning: Refer to Safety Glasses and Compressed Air Warning in the Preface section.
Caution: Clean the spark plug recess area before removing the spark plug. Failure to do so
could result in engine damage because of dirt or foreign material entering the cylinder head,
or by the contamination of the cylinder head threads. The contaminated threads may prevent
the proper seating of the new plug. Use a thread chaser to clean the threads of any
contamination.
2. Use compressed air in order to remove debris from the spark plug cavity.
Caution: Allow the engine to cool before removing the spark plugs. Attempting to remove
the spark plugs from a hot engine may cause the plug threads to seize, causing damage to
cylinder head threads.
3. Remove the spark plug.

Caution: Use only the spark plugs specified for use in the vehicle. Do not install spark plugs
that are either hotter or colder than those specified for the vehicle. Installing spark plugs of
another type can severely damage the engine.
Caution: Check the gap of all new and reconditioned spark plugs before installation. The preset
gaps may have changed during handling. Use a round feeler gage to ensure an accurate
check. Installing the spark plugs with the wrong gap can cause poor engine performance and
may even damage the engine.
1. Ensure that the spark plug gap is equivalent to the spark plug gap specification. Refer to
Ignition System Specifications.
Caution: Refer to Fastener Caution in the Preface section.
Caution: Be sure that the spark plug threads smoothly into the cylinder head and the spark
plug is fully seated. Use a thread chaser, if necessary, to clean threads in the cylinder head.
Cross-threading or failing to fully seat the spark plug can cause overheating of the plug,
exhaust blow-by, or thread damage.
2. Install the spark plug.
Tighten
Tighten the spark plug to 20 N·m (15 lb ft).
3. Install the ignition coil(s). Refer to Ignition Coil Replacement - Bank 1 and/or Ignition Coil
Replacement - Bank 2.

Thanks for all the info. I didn't know it was going to be this big of a pain to do a simple spark plug replacement. It's nothing like working on the old small block.
