i need help please if anybody knows of any install guide links please tell me

 

install guide for what????

 

for spark plugs, air filter, and flushing out radiator

 

I'd try shbox.com or search the forums here for peoples advice. Spark plugs are a pita. You have to remove your exhaust manifolds or headers. air filter should be pretty self explanitory. i think shobox has a radiator flush guide (not sure though)
