Just put a nismo CAI on my G and i like the intake sound....but i think i lost power...i checked leaks...i had the engine light for 3 days after install but its gone....is it normal???....I know intake really doesn't make large increases..i think I might have gain in the top end but def. lost the bottom...i understear during u turns.....I used to get the back end out with little effort ....hmmm...anyone know whats up???

 

bump someone help him/her

 

nope...still lookin for some help ....someone told me on my350Z thats the longer piping in the dif. in the air is causing my ECU to be slow?? ..

 

The only thing I can tell you is that when I installed my Nismo CAI the check engine light did not come on at all.

 

Oh did you remember to reset the ecu?

 

i installed mine last month and got no engine light either. i didnt reset my ecu either cuz i heard it resets itself after a short time. as for me i didnt notice a gain OR loss though i 'felt' things we're flowing better. makes sense? i didn't even notice sound changes until a few days later. i installed it myself and being a NOOB, i read things over and over carefully to make sure i did everything right. you might want to check your MAF? OR take it off and reinstall the OG set up and check to see if eng light is still on(PITA, i know). good luck man

 

The light has been off for along time...i'm not talkin about the LIGHT,,but thanks.....i didn't reset the ECU.....but i think that will happen byself...well thanks for the info...keep it commin maybe someone can help me....

 

I have the same intake and the light did not come on after install..
i agree with tinman143 as it just makes it breathe better..

 

i have the CAI installed in my g a couple months ago, there were no check engine lights that came on. i didn't do a reset either. felt no loss or gains. i know that didn't help much, but i guess you should reset your ecu.

 

Does anyone have a copy of the installation instructions for teh NISMO CAI? I just bought a used one and it didn't have teh installation instructions.

 

Instructions:

Take old stuff out, put new stuff in. Don't get your MAF or throttle body dirty. Intakes are VERY straight-forward, and pretty hard to mess up.

 

did you take off your maf sensor (unplug it)? if so, did you turn on the car while it was unplugged by chance?

 

Figured as much, but I am not 100% sure where everything goes and if I truely have all the parts. If I could get a copy of the original instructions with a diagram that would help, as I do not have any instruction to start with other than take stuff out and put new stuff in.

 

Has anyone dyno'd their car before and after their Nismo CAI install?

I installed a Nismo CAI with DC headers, a Z midpipe and an HKS muffler on my 05 sedan with Revup motor a few months ago. When we put my car on the Mustang dyno before tuning, my car was running very lean with a 40 hp loss somewhere after installing these mods.

Although I have gained the power back after tuning, there were no gains either. The baseline I compared those runs with were the before and after from when I first installed the MREV.

I'll be spending the next week or so re-installing old parts to see which is giving me the power loss.

 

looking to buy the nismo cold air intake, from what i am reading have second thoughts, is it really worth the money if it does no good?
