I just bought a 2001 Infiniti I30 (basically same as Maxima). I want to start doing mods; first being either a K&N air filter or CAI.
1) Do i have to break it in first? If so how many miles?
2) I was looking at the engine before; how do i remove the stock air filter? Thanks.

 

Start with a Stillen high flow intake and a Stillen Y-pipe.
Look at the "Instructions on how to" section on the 5th Generation Maxima section.

Congrats on your new purchase, welcome to the forum!

 

Welcome, welcome!
And yes, there is a break in period. 1000 miles of h*ll where you must baby your engine and be nice. No redline, no hard starts, and no keeping the engine at the same rpm for long periods. It sucks, I know, I just finished mine, deflowered my baby at 1036 miles. But, the wait is worth it, read my post 'to redline and back' if you want to see how excited i was. Great cars and great engines.

 

Go with CAI all the way, i know i am pretty soon

 

Congrats and welcome to the .org!

let the modding begin!

 

congrats a CAI would be a good start. I would wait until 1k miles before modding it though just so it breaks in a bit.

 

Thanks a lot guys

 

break in isn't really necessary. these days, new cars already come broke-in anywayz....

 

But you get better gas milage and less overall problems if you let the gaskets seal properly over the first 1000 miles.

 

Ok, so pick one; a CAI, or a Stillen High-Flow intake?

 

If you BOUGHT the car, the CAI, it involves cutting a big hole in your fender, if you LEASED the car, the high flow, its a bolt on.

 

Which has better performance? I bought the car, but im not too sure about cutting up the fenders and stuff.

 

It's really hard to accurately dyno a CAI, the benefits are realized only when moving and actually getting cooler air. IF you have a auto, I would suggest the CAI (many auto owners report a lack of low end torque), if you have a 5 speed, then go with either, most because if you think about it, once you starty moving the air inside the engine bay won't be as hot anymore.

 

Give the OSCAI a shot first.

 

performance wise its pretty close...just depends if u want to drill a hole in the fender of your car, if u dont mind the hole, i think it comes down to sound, the PRCAI is louder than Stillen, ive had both, i got the stillen first and then heard my friends ITR with a Iceman CAI...and i was like...i need more sound, PRCAI sounds louder and more aggressive but after about 5k RPM engine sound takes over, but its great sound after driving it around a few days.

 

Im probably just gonna go for the regular $40 K&N air filter for now. I opened the engine, but can't open the air box to take the stock one out. How do I go about doing this? Also, should I remove the air silencer? Thanks.

 

There are two metal clips that you snap back to release the filter tray. Pull up, and there is the filter. If you have a 2k1 model, you will notice that there is no silencer/L-tube for you to remove. If you have a 2k model, you can remove the L-tube. Adding some flex tubing to the end of the tube and route it down to the splash guard to make the OSCAI. If you have a 2k1 model, you will need to cut the bottom of the air scoop since it is sealed.

thanks guys

 

ok, that worked, but i opened it, and its a screen-like filter. If i take the whole thing out, then i can put a conical filter in? is there ne thing else I have to do? thanks.

 

to stick a generic cone filter on, you will need to remove the whole air box and probably get an adapter to make it fit. Or, you can get a stillen or JWT intake.

 

The JWT and the Stillen look just like a K&N; u sure there a big difference?

 

a number of people who had the PRCAI actually converted back to the Stillen set-up. basically, there was only a temperature difference of 1 degree, and almost identical low to mid range power. however, when it came to top end power, PRCAI topped out less hp than the stillen, as BrianV and Cheston both complained that their cars were topping out too early with the CAI set-up...

 

that makes perfect sense bc at high RPM the friction in the tubing for PRCAI seems to kill its power beyond 6000 RPMs...but since intake HP increase is relatively small i chose PRCAI for its sound...hehe...the sound isnt really clean...if u rev while using WOT, while in park...u can hear the intake, its loud but after about 4000-5000 RPM..the engine noise is much louder.

 

how is the K&N air filtercharger different than a still high flow intake or the JWT?

 

WELCOME! You should have came here first and bought my 2001 I30T, all the basic bolt ons are already included

Also, if you get a Y-pipe, all I30s are 50 state spec, not 49 like some Maximas.

 

Why are you selling so fast?

 

Want to get something different, maybe German, and with a 5spd

 

You're still sucking air in through the same maze of pipes and a slilencer when you use the K&N.. with either Stillen's or JWT the filter is right past the MAF sensor.. and it's wide open....

I think the only intake on the stock is that ram-air like thing at the front of the hood... it's not very wide when you look at it compared to the size of the tubing around the maf sensor...
