Now in the case of this car in N/A form the gains would be very minimal. Personally I would need to see a dyno chart comparison to believe there would be any gains.
However, if it was my car, for the minimal cost, I would probably invest the money in them for peace of mind!

Ive had the tubes before and now I actually begin to question if the slinky/ribbed style tubes arent actually beneficial. if you look at several high performance vehicle engines (lamborghini, ferarri, vipers, corvettes) they all appear to have the slinky style intake tube. There must be a reason. I doubt its for sound, mpg or emissions. Maybe the ribs cause just the slight amount of turbulence actually needed for smooth air intake flow. I also wonder if maybe smooth tubes are beneficial on forced inductions vehicles? Ive had numerous intakes both CAI and SRI as well as silicone tubes on the VQ.
