Better and much safer than starter fluid is propane. While both can accidently ignite with a spark, with propane you'll just light the torch, which you can quickly pull back and away. With starter fluid, you ignite everything that the liquid was sprayed onto.
Take a propane torch (open but not lit, of course) and run it along everything on the bank1 side of the intake.
