RC engineering makes them. You can find their ad in any of the tuner magazines. As for prices don't know. FYI you don't need bigger injectors unless you have a turbo or a dry NO2 kit running above 50 shot. A wet 80 shot (max on stock engine) doesn't even require injectors. This was told to me directly from RC Engineering themselves. And if a company that I ask a question do I need this and they say no. I would tend to believe them. smile.gif

 

Try Balistic Racing S.A - 550cc 16ohm Lucas injectors for $60.00 each ($240.00 for 4)
