This new filter has probably affected the MAP/MASF sensor because the air flow has been altered . The word performance will be the clue so you may have to find a speed shop with a chassis dyno and have the chip remapped to the filter.

1. if you took away ducted cool air plumbing and now have a K&N sucking in warn engine bay air its entirely possible

I assume you are referring to the spark plugs? If so have a look at this page for your answer: http://www.iwsti.com/forums/how-install/159039-2008-gr-sti-spark-plug-install.html

First off before you do anything locate and know where your oil pan is and your oil filter. Your pan will be accessed from under the car and will have about a 9/16 bolt on it. That is your oil pan drain. Find your filter which will be most likely on the front right of the engine. Get a pan under the oil pan plug, take off your oil cap in the engine, and unscrew the drain plug. As it is draining take off your oil filter with a filter wrench. You will most likely want something to set the filter in when you loosen it (it is full so keep it upright as possible) Let it drain until all is out, replace the filter, put the plug back in and fill with the recommended amount of oil. Turn it on for about 15 seconds and then off. Check for leaks at the plug and filter and tighten if needed. The filter does not get "cranked down". Don't forget to put your cap back on the top side and you are done. Before you close the hood check to make sure the oil level is in operating range marked on the stick.

most likely driver door lock jams while trying to lock.

If you had a flywheel replaced it is possible that it is not reinstalled properly. Check for engine vibration at idle . Check that the starter is in correctly. IT appears that the starter pinion is not meshing correctly with the ring gear and that is your noise . It goes after starting because the pinion disengages from the ring gear. The problem is a misalignment between the pin ion and the flywheel ring gear ( nothing at all about polished gears ). IT is all in the installation of the flywheel -starter and gear box.

I am sorry I have no idea where they might be because I am not there to see where they feel into.

Take a thin utility cord. Tie it to one end of the front bar and wrap it repeatedly around the bar to the other end of the front bar (spaced about an inch per loop, working around anything attached to the rack) where you tie it tight. Can disrupt the airflow to break the noise - got rid of all of the noise from my rack. I used a 10 foot cord cost $1.60. Doesn't look as cool as a fairing, but much cheaper and no one will steal it from your car. And you don't have to move the bars so that you can't use them.

Well technically you have fuel in the engine if you are getting a backfire in the intake. I would say the fuel is getting thru the injectors.But maybe not at the right time.Has anything happened to the timing belt or cams ?

bring it back could be a faulty clutch. joe
