NNBS/TBSS INTAKE ON A 5.3L

[Maximus1]

I would like to know if I convert my intake to the NNBS/TBSS on a 5.3L will this help or hurt my horsepower? Has anyone else done this on a 5.3L? I've read write up's on doing this with a 6.0L and had dyno proven gains of 20-25 HP. Just curious if it's worth my time on a 5.3L. Thanks

Yes it is worth your time. It is good for 15 hp or so. Plenty of writeups on it on performancetrucks.net

Will the swap work on the 2004 L59 Flex fuel engine? I have noticed that the Flex fuel intake is different in several ways not just the fuel rail
