i have an 04 with 58000 miles and after a compression test yesterday, i got results of 7.0 bar on the front rotor, 6.5 rear @250 rpm indicating my engine was failing. before i take my car into a dealership for them to check it out and run their tests, i want to make sure certain mods will be okay.
the three i'm worried about are an AEM intake, the BHR ignition kit, and underdrive pulleys.
i know the pulleys i will most likely have to revert to OEM. but would it be better to switch back to the stock airbox and coils/wires or will that not be an issue?

 

The coils and a non stock AccessPort tune can be a used as a way for them to not pay for the motor. Would they however noticed the coils during the compression test? When it comes to a engine I would make it as close to stock as possible and not take a chance.
