how eazy is it to clean secondaries, would you sugest cleaning it with and how about getting them out of the car, just a thought b/c i know im ganna have to do it sooner or later

 

You can do it in three different ways: (from cheapest to best )

1) Throw in couple of injector cleaner bottles for 3-4 consecutive full tanks.
2) Take them off and clean them using a strong detergent
3) Take them off and have them ultrasonic cleaned

First one costs around 10 bucks, but will yield minimum results. Third one costs I think 100$, but you'll have almost brand new injectors
