I serviced my 2015, Spyder RT yesterday. I changed the oil (Valvoline 10W-40 Synthetic) oil filter, gas filter, and K&N air filter. It did take me about 2-1/2 hours but I did some cleaning at the same time. The gas filter is kind of a tricky thing to get at. Total cost of parts was $125.50. The K&N air filter is a little high but I will never have to buy one again. I don’t know what a dealer would charge for this but where I live I would have to make an appointment which would be a week or so and leave the Spyder. The closest dealer would be about 50 miles. I also did change the drain plugs to Gold Plugs they were $43.97.The Spyder just had 20,000 miles on it. The air filter did not really need changed but since I had the K&N filter I went ahead and changed it. I also doubt if the fuel filter needed changed. I had already bleed the brakes. My next oil change it will be time to change the transmission filter and I will probably replace brake pads. Other than that I should not have do anything to the Spyder for the rest of the year.
