Ok gang...here's the question:
Which is better and why: Stillen air filter intake kit w/ z-tube or full-on Injen cold air intake with the long tube setup?
In a nutshell, the numbers are similar dollar wise, but the Injen takes a whole afternoon to install...which I don't mind (my girl would argue this point since it will probably take me all weekend)
Anyway, what I'm looking for is professional G35 owners/tuners to share their honest opinions about the advantages/disadvantages of either system based on their personal experiences with these systems. For example: Are the Hp gains really true or just very inflated? Anyone find any fuel economy by adding these systems in or is it just hype and everyone is syncopating to run with "talking heads" gang?
Any valid advice anyone has to offer will be very welcome and appreciated. Suggestions for a newbie to G35's would also be appreciated.
