2002 2.5

The sale price for the Maxima midpipes are as follows:

2000-01
$55 Midpipe kit only
$109 Full intake kit with K&N filter
$159 Full intake kit with Apexi filter and adaptor kit

2002-03
$49 Midpipe kit only
$105 Full intake kit with K&N filter
$155 Full intake kit with Apexi filter and adaptor kit

Shipping is $10 for any of the above kits.

I'll post some more pics on the website as well as an order page by this Sunday. In the mean time just send me Paypal payments to: sales@berktuning.com

 

hows does it perform and how does it sound?

 

I have similar intake, made by FrankenCar and it sounds great and performs great. Sounds really loud when you floor it. Really nice growl.
Cars pulls harder too. It also makes this air sucking sound, which I like, sounds like a bov on a turbo

 

Does the kit with the K&N come with an adaptor kit?

 

When using a K&N filter, the adaptor kit is not needed.

 

GREAT!!

Glad that I pre-ordered mine! I'll be watching for the delivery truck dude!!

thanks,
Chris

 

looks shiny

 

QUestion,

is this the one where the MAF is integrated in to the intake??

HOw does this work with the 2002/03s??

The one with the maf adapter boilt into it is made by Firm Fabrications

cool

what is the difference between yours (coby) and the frankencar??? midpipe? is the diameter bigger?

 

what is that integrated MAF thing, i heard it here one time and i didn't get it

 

Does anyone have that yet? Wouldn't that lean out the mix since the inner diameter is larger than the stok MAFS tube? More air passes by at the same given rate?

I guess that would be a good thing, but that would make they're intake look like it performed really well, when it was really tricking the ECU.

 

Here's what's different:

1. Polished 6061 Aluminum vs powercoated galvanized steel
2. Seam welded joints (metal is all one peice instead of using welding rod as "glue") vs TIG welding
3. Thermal Flex silicone hose custom made vs Nappa Autoparts coolant hose
4. PRICE $109 vs $140

The aluminum piping has a slightly larger internal diameter than the galvanized steel Frankencar piping. However, the difference in performance from midpipe to midpipe would be negligible.

 

What will that do for me? And how hard is it to install?

 

very easy to install... your basicly just taking out your stock air box and replacing it with a midpipe and air filter. Gains are proly about 5hp-8hp not too too sure youll gain alot of topend but loose very little low end.... ive got the berk intake and im about to get that midpipe when i get the extra cash... plus your engine will growl at WOT wich everyone loves hehe

 

I need to get you guys a shot of the welds. They came out soooo nice!! I'm totally pleased with the quality my fabricator turns out for me. I'm sure glad that I got to know the right people in this car industry!

 

looks nice, i'm a fan of polished myself

FIRM fabrications integrated MAF eliminates breaks in the tubing walls. works on turbulence as the principal. similar to having your head ported & polished but did'nt port match the intake and exhaust manifolds. the ridge or step that is now created by enlarging one and not the other causes the air to tumble and decrease the air velocity. when you break the tubing wall and use hose clamps, there will be a slight gap, dip, or ridge even if you butt them together. it has been thoroughly tested. the stock fuel and ignition maps contained within the computer has the ability to adjust for descrepencies in airflow, low octane gas, limp-in mode when a sensor fails, etc...

 

I don't know what you are saying... as I understand, the MAFS has a tube of a given size that measures air flow with a heated wire at a single point. If you increase the size of the MAFS tube, more air will pass through the entire tube at the same given rate for the MAFS sensor. Therefore, you would be putting more air in the engine then the MAFS accounts for, ie LEAN. This will probably make more HP, but you will be tricking the computer and running lean, which COULD cause problems...

 

The ECU knows exactly how much air is being ingested and will make any corrections needed with fuel to accomodate the additional air. But what FF is saying about all this turbulence and such would not make any measureable decreases. Their parts does look nice though but carries a heavy price tag.

 

Do you see what I'm saying? Think about how the MAFS works, if you increase the diameter of the tube, then you don't have an accurate measure. Remember the tube SR20DEN made?

I just think that if it does indeed change the amount of air the ECU see's, then it would be nice to know exactly how much. Maybe it's minor, maybe not.

 

Even if you had every bolt on available for the Maxima, you would not run lean. SR20 had like a 3.5 or 4 inch intake tract. In the case that we're talking about, we are talking about a few MM's of difference if even that.

 

I'm saying lean as opposed to stock, maybe I'm using poor terminology, but you get the idea. All I'm saying is it does change the size and flow character of the MAFS tube. I never said it would be detrimental, just something to know.

 

YEA! I want one! I checked the website coby, but I couldn't find a spot to order. Email me or something so I can get my hands on one! I like the cheap price as well, us dang poor college kids.

 

Bryan,

I have sent you an email and PM...when are you shipping the midpipes. I sent my PayPal payment about 12 days ago. Please let me know.

Thanks

 

I can't seem to find the thread on the colors for the vacuum hose.

 

these things are available for the 2k right? it looks like the pic would be for a 3.5, where would all the vacuum lines in the 3.0 go in this pipe?

 

cobymoby,
will this midpipe work to just replace the current rubber flex pipe, and still keep the stock airbox and filter?? i'm looking to improve flow, but don't want the sound associated with the open ended filters.

 

Have you heard a Maxima with a open ended filter yet? Quiet as stock under normal driving and a deep BMW type growl when you open up the throttle. It doesn't sound like the Civics.

 

I'm pretty sure the ECU can adjust for variations in the MAF. It does this by monitoring the 02 sensors. Over time, I think it will adjust the value of a correction factor for the MAF readings . . . After all, if the ECU knows the amount of fuel added, and the amount of oxygen left after combustion, it can adjust the MAF readings to be properly calibrated . . .

 

yes, i have. i used to have the place racing CAI and i also used to run a hot air type intake. it's the growl, which i don't think BMW's have, that made go back. i liked the sucking sound that came from the CAI on throttle, but that's all i liked about it.

 

is this guy still around?

 

NOPE

 

Took everyones money and ran for the woods. Unless something fatal has happened in which case I'm going to hell for making the previous statment.

 

Steve from FrankenCar has great customer service and always responds to your questions. FirmFabrications has never responded to my emails. JWT and Stillen both make POP chargers.
