Alright guys, thanks for the replies, the consensus is that I will not see an increase in fuel economy. Kind of a bummer since, I was justifying the price based on the long term savings, but I guess that won't happen. Now I just have to decide on which CAI to get, stillen, takeda, injen.... so many choices

 

Meh, you can find someone to say why each is the best but regardless, they are all proven to add some power. Some cars see 2-3hp, others see 12-15hp so with that much wiggle room before a tune, you may as well go with the cheapest or easiest to install. That would be the Takeda or Injen. Stillen requires some cutting.

 

How easy are we talking?, I have little car experience asides from the occasional ol change.

 

Well the bumper will have to come off regardless which option you take, could probably get away with leaving it on for the Injen but it will def make it harder. I'd say the Injen is easiest, just unscrew and bolt things on, no modifications or struggles. The Takeda is next but the couplers are a tight squeeze going through the holes and getting it all to match up is a challenge. Last would be Stillen, if you've only changed oil, I wouldn't recommend cutting into the car without a second set of hands. All that being said, installing any of those intakes is like a 3.5/10 on my scale... There's a few videos on YouTube of the 370z and g37 intake install, they are practically the same. Check those out for a better idea.

 

Thanks a lot, I will definitely check out those videos!

 

The Stillen doesn't require removing the bumper cover, or at least I didn't. People always seem to make cutting the core support a big deal, but it's really not. I took a small craft saw to it and was able to make the hole big enough (and clean, too) with just that. It's fairly straightforward even for a beginner. Just might take some time.

 

I went with Stillen Gen3 because I saw an amazing offer so could not skip - Gonna install it this weekend, I don't think it's going to be all that tough. But I will find out

I did a lot of research and went with Stillen.

 

Was this a Black Friday or Cyber Monday deal?

Through a myg37.com vendor?

 

Oh yeah!!!I bought it from Imports Parts Pro yesterday and it will dock on Friday - Can't wait to install it

 

Permanently cutting pieces out of your car IS a big deal. Especially for resale or warranty reasons.

Now, the actual cutting part is a piece of cake but the OP said he's hardly changed his own oil so I figured it would be best to not make his first project one with some custom cutting/fitting lol.. Just my opinion though, he knows what he's capable of more than any of us.

 

No, that's definitely fair to say. I was more referring to the actual act of cutting, which as you said, is a piece of cake.

 

I wonder if some of the lack of hp is due to the cars not getting tuned afterwards. I doubt you will see a gain in mpg unless you get off the gas.

I bought some Mobil 0w30 which I worry might be too light, being that these cars have the rear timing cover leaks. I think most of the time it has had dino oil installed. I asked the sales guy what oil was put it, he said, probably conventional.

 

The aFe is almost identical to the stillen with the exception of the filter setup and only a fraction of the price.

PM for details.
