Non-foulers are just spacers for the O2 sensor that sort of reduces the exposure to the exhaust gas. Most HFCs I've seen pushes the O2 bung back from the stock position and have non-foulers. It's all to help avoid the SES or CEL light.
Are they those L shaped devices I've seen in photos?
Ease of install/maintenance... R2c. There's a deal in the Group Buys section.
did you notice any drop in torque at the low end after installing the R2Cs? The excel test reports on their site show a pretty significant drop on the bottom if I'm reading it right (kinda weird formatting)...
did you have them on before the HFCs to be able to tell difference with/without?

Had an R2c on my Maxima... don't have an intake yet on my G... but eventually... I'll be going with the R2c for sure though.
Ok, yea, I almost pulled the trigger on the Injen CAI and then had second thoughts with the whole bumper thing, not so much for the install but go forward maintenance, so now debating between that and the R2C...separately, I just got the HyperTech programmer so will post back after installed; haven't had time to do anything with it yet, but decided to do that first against stock everything else and then be able to gauge the additional mods from there...
