What to replace when repairing airbox?
 

It looks like I'll be removing my airbox soon to check for breaks. If I can fix it, I will. Otherwise, I'll replace it. What should I replace when I do this?

Popoff Valve, if the new one doesn't have one
Intake runner boots
CSV and seal
Airbox Seal
Coffin Gasket (?)



Anything else I should replace?

Paul,

With the air box off, check all hoses that typically are unseen--those between the engine and the firewall. Look closely for age and cracks and replace any suspect hoses to the CIS components, especially the large hose to the AAV and AAR.

the sleeves that connect the air box to the aluminum intake pipes are often shot. Be careful when ordering there are different sizes.
