WHY OEM INTAKES and FILTERS ARE BETTER

I won't waste my breath, no one here cares about facts and engineering...

I just want my ice cream.



Though, the butt dyno is really what matters most (as said before, but I just like the term "butt dyno").

Just ordered one.

Some people probably do it simply for the fact of getting a more "sporty" sound out of the intake since the factory intake is designed to be quiet.

Agreed. Close this thread of stupidity.

Before this thread gets locked, I'd like to state something. I think the extremes of both sides of the argument are unfounded. On the one hand, you have a guy stating that 80% of CAI owners will return to stock. I don't know where he got those numbers from, but I suspect they're a tad...off. The guy's original post sounds a little too "propagandish" to me.

There's no doubt that there are numerous dyno sheets proving the gains of the installation of just a CAI. However, these dyno sheets are also a marketing tool. The results will be the best run on the best of days, under the best of conditions. I don't know how much they would pertain to the harshness of daily driving. Would the loss be more on the hottest, most humid day? Or would they be minimal because of the added air stuffed into the block? We really don't know until someone runs stock and modded on a dyno EVERY DAY.

Bottom line? I don't think the loss is as bad as some people state, and I don't think the gains are as great as the sheets will lead you to think. Swing away.

I will be at Z-days, I would love for someone to ride in my car with stock intake and only thing I have is a F.I CBE. I bet my car will feel more alive. Then someone with tons of bolton's

My case I have spent about $3000K on intakes for all my cars and all of them lost power and GAS.. Oh and I had the NISMO intakes on my 350Z NISMO 08 HR and it lost power.

lets make sure our butt dyno's are calibrated before making any serious statements.

This has got to be one of the most pointless threads ever. The OP's arguement is basically, what's the point of spending all that much when all you see are small gains until you reach the peak powerband. The thing is, we're looking at the Z as a performance car where every hp matters. There is absolutely nothing wrong with going OEM and keeping everything stock. At the same time though, there's nothing wrong with some engine bay bling or a few extra pony's. You don't have to hit the redline every time you drive, but it's nice to know it's there. If all I did was drive the Z like an old lady, I would have been better off with buying an FR-S.

Modifying your car with aftermarket intakes and exhaust has nothing to do with logic or common sense. It's fun. YOLO

Yeah but it's good for several pages of forum entertainment which is why we're all here reading this anyway.

My background is I.T Engineering! and I look and feel and research everything to death!

I can't get out of my head as to why NISSAN pulled HP number from NISMO and IPL to 350HP 348HP with just high flow CBE and tune.

The intakes did not change!

NISSAN has pulled everything they can out of the 3.7L setup! so why on earth do we think an aftermarket business like Stillen or Injen knows best and is able to make more HP then OEM???

If that is the case why does NISSAN pay there engineers $100 per hour to get as much HP as they car? why not just build a setup like Injen or Stillen?


I understand you want that added HP at 6500K but at WOT with OEM, I don't feel anything more or less with the Injen setup just that the Injen and Stillen are louder!!

I took apart my whole intake setup and after looking at it, it's very good design.

So why is the aftermarket setups making more HP or seem to be?

I will be getting my car dyno at Z-days to see my WHP with stock intakes and F.I CBE with tune.

this is because aftermarket companies are TRYING to get max performance. Nissan just bumps it a but to make you pay extra money for a nismo or IPL.

aftermarket makes more power because that's the point. free up HP that OEM denies.

look at the GTR. intake, exhaust, and a tune and the thing can jump up 100AWHP just by taking away air restrictions.

you say you research this all to death but i feel like you havent. possibly just stuck on the idea OEM is better? i dont know why but you need to realize it's not

i'm not sure now if you're trolling or just stupid at this point.
