WHY OEM INTAKES and FILTERS ARE BETTER

Although my '09 had a CAI (more like a WAI) and a car delete y-pipe (Maxima has 3). And the 2013 will have the same mods soon as well as probably a plenum spacer, and I already have a Stillen UD pulley for it.

The acceleration of the Maxima is as good as it is due to CVT, it allows you to stay on peak power all the time. But the biggest disadvantages weight, you can't dyno it properly, it can't take much more than 300HP, and I BET the loss to WHP is worse than on a regular AT

Yuup, I know. Very verse on Maxima's as I am with Z's, have had several of each and like them both.

If you want value on your return, you obviously get something more economical and mass produced. However most people that buy a Z fit into two categories. They want a Z and it is the epitome of fun for them, or they buy a Z because they can afford to buy it, enjoy it, and sell it to get their next fun car at their leisure. Modded or unmodded has nothing to do with either.

Of course it's going to smoke lots of 10 yr older cars... That's the nature of advancement. But whos to say the "new" developments 10 years ago in their prime didn't mean the golden age of automobiles, some would say the muscle car era was the peak due to the fact no one cared about emissions or restrictions. It was build a good looking car, put the biggest motor you could find in it, and melt tires.

I would add that this is the golden age of autos as we get the most stock performance for the buck at the greatest level of efficiency. Cars are better performing now, but I think are also at about the same price as 10 years ago (in constant dollars), while slightly more fuel effiecient. What seems to be happening now is that performance is staying the same while efficiency (MPG) is improving. Thats what seems to be the trend for the medium term. So the best time is now.

MPG is all BS. Sure cars will improve in terms of MPG. But what will be the result? People will just drive more effctively negating the lower pollution from efficiency gains (assuming gas prices remain constant). From an environmental perspective, high gas prices are good- people drive less and thus pollute less, and use less resources. But I'm rambling now.

Guys the point I am making is the stock intake system is very good! and all the money in the world with buying aftermarket CAI is not going to get your no more then 4-6WHP.

I bet you 80% of time people who buy aftermarket CAI end up putting them up for sale in a few months? why because they wake up and see they lost $500-600 on something that only looks good and gives more sound!

Unless you are tracking your car and running near 6500Rpm with CAI you would get more topend power.

But that's it!

we dont care!

the point of this thread is maxima drivers think they drive SPORTSCAR.

jk the stock intake is pretty good. good enough to be used on the amuse 350Z racecar when that gen had the dual intakes.

At the end of the day, 90% of these threads turn into a "Who's got the bigger díck now?"
LOL

I've been through lots of cars and the usual 10hp bolt-on mods designed to empty my wallet but now that I'm older and having gone through all that, I'm proudly keeping my Z intakes bone stock but investing in Viagra instead.

OEM Filter fanboy???? thats a new one. glad i swung by to see this thread of non-sense

it just keeps getting worse

this sounds more or less like someone who got sucked into buying a CAI and never takes their car above 60mph or revs hard.....or drives it like it was meant to be driven. go back to stock and quit bitchin bout it.

there's a complaining thread for that. go join the 4 girls in there and have at it.

that is all.

Every person except GTLAW (GSXR750 too) must be wrong. Somehow all the empirical evidence we have gathered is wrong too. We are all doomed. The minimum whp expected is 10whp on a modded car, and more as a first mod. The stock intakes are good, but CAI's will create more power, and more than the 4-6 you claim. We should just spam this thread with dyno results.

Bottom line is stock, second line is full exhaust, 3rd line is CAI and pulleys. Looks like my low end has dramatically improved as well. The dyno must be lying.

Hawk -So lets clarify your dyno chart.

Bottom line is bone stock. ?

Middle line is full exhaust. ?

Top line is full exhaust , aftermarket CAI and pulleys ?

If I am correct then where is your dyno chart showing the big HP gains with just a after market CAI , nothing else.

KERMIT · 04-02-2013, 06:26 PM

I would post more but don't want to cloud this topic with factual information. Has anyone performed a gage r&r on these Dyno's.? Please show me the design of experiments where you can isolate the "intake" variable

Too many opinions. Not enough data. Those that throw out Dyno plots should also understand their repeatability when discussing small gains.

Pay for it and I'll oblige. I can still guarantee gains much higher than 4-6. It's also well known that the more breather mods added, the more diminishing returns. Getting 16whp from an intakes and pulleys is impressive. Subtracting the 5-7 peak whp pulleys actually make is still far and above the stated claim. Let me remind you something I told someone else here. In this world, 1+1 is not 2. AEM, Stillen Akuma, and AAM have seen gains of 15-18whp on a stock vehicle. I suppose they are lying too. I'll be more than happy to pull their dynos for you.
