Cold Air Intake

[NYMARAUDER]

Hello ladies and gentlemen. Just bought an '04 2 weeks ago and the car is amazing. Considering adding a K&N cold air intake. Does anyone know if I have to purchase a tuner or can I just swap the intake out. Any feedback will be much appreciated. Thanks. NYMARAUDER

[David Mathis]

No tuner necessary just a quick swap shouldn't take no longer than 30min

[NYMARAUDER]

Thanks. That's what I was hoping.

Welcome to the owners club NYMARAUDER! :beer:

While you consider a cold air intake for your MM, don't forget to look at the JLT Ram Air Intake Kit (https://www.jlttruecoldair.com/ZenCart/index.php?main_page=product_in fo&cPath=524_527_93_94&products_id=65&zenid=ok65osiagkvgfumvsccnurib 62) as an alternative to K&N. Just a bit of advice. :)

[NYMARAUDER]

Thanks for the advice. Do you believe JLT is comparable or better than K&N? It's a lot cheaper.

Performance gains are similar. Many feel the K&N is more aesthetically pleasing.

If you do not have a performance tune, get one! Best mod you can do w/o boost. Marty at Mo's Speed Shop(vendor here) can get you what you need. Stay away from the canned tunes, they are not as good.

IMHO... . JLT FTW!

Jlt does look way nicer to.

My IAT datalogged temperatures with an underhood "cold air" kit versus the stock airbox on a 90deg day, on the same stretch of freeway, at WOT were 11deg F *higher*. The factory air box does a much better job of routing cold fender-well air into the engine than any kit that sucks hot under-hood air.

On the dyno, with the hood open, the cold air kit made 3rwhp. I never tried it with the hood closed. This is comparing a 60K mile old used motorcraft panel filter, by the way...

I think the gains are far more significant if supercharged. For stockish power levels, I don't think there's much to gain here.

If what is stated here is generally true the K&N/JLT CAI's are more eye/ear candy.

ByronRACE did you ever try the K&N drop-in filter in the stock air box?

Never did; I'm not a fan of the oil/gauze filters. I spent too many hours cleaning MAF sensor elements to correct contamination induced fuel trim problems on customer cars. I run motorcraft paper filters on my street cars.

I wrap the oil style filters in paper towels and let them sit for a few days. Helps get some of the excess oil out of them. K&N's so far have been pretty good from the factory at not being over oiled. No issues with the MAF's on either car so far. Have a dry cone filter on the truck from Airaid.

We really like the JLT...

[martyo]

Let me know when you're ready for a tune.

It will change your life.

+4, +5,

JLT FTW

What-you-already-have ... the OEM air input system is already CAI. inlet air is drawn from the front of the vehicle thru the header panel.
the airbox is sealed to prevent engine bay heated air from being drawn-in.
the system is made of plastic which minimizes heat transfer and/or heat sink.
.
the OEM air input system is MORE than adequite to provide air flow. *CAVEAT: UNLESS ... The engine has been HIGHLY modified. e.g. cams, heads, forced induction (when it was originally NA).
.
ANY CFM increase comes at the expense of air filtration. MEANING: less.
.
oiled air filters may/will/do contaminate the MAF sensor.
.
non-sealed filters draw heated air from the engine bay increasing IAT (Intake Air Temperature).So ..... Unless you're considering an aftermarket offering for its increased growl and/or engine bay cosmetics value, invest your $$$$$ in a tuner since there are little to no performance gains to be had with an aftermarket CAI.

.Just to add to the above the OEM intake was developed in conjunction with Roush performance.

To improve performance with the factory intake ,open the metal clamp up on the walrus tooth on the side and remove and insert a rattle can paint top inside it and reinstall the tooth ,this will improve air flow [ a little more noise also]
