We have seen very undesirable results with the oem spark plugs when developing our maps.  

One step colder plugs are a requirement on our tunes to ensure smooth operation.  We recommend NGK Part # 6510 spark plugs gapped at 0.025 - 0.026. 

You can buy these plugs at most local auto parts stores.  Please be sure to properly gap each plug as improper gap specs will create knock!
