It's weird. I went to Checker Auto, Autozone, and Walmart looking for the air filter for my 05 GT and although it is listed in the Fram catalog (#CA9895), it is not available anywhere. I guess I'll either have to get a Ford filter or order it on line. With such a popular car whey can't you buy the air filter. My car only has about 3200 miles on it (not a daily driver) but the filter has some dirt in it so I thought since it is about 1 1/2 years old I'd change the air filter. Weird! Oh well ??

 

Lucky you. It was in the cards. Do NOT put a Fram in your Mustang. Bite the bullitt, do it right, go K & N. yep even for a drop-in, it is well worth the investment. If you really don't want to,or can't splurge, then try Bosh or Motorcraft.

 

Hey Don I got a new K&N I 'll sell you cheap! its posted in parts for sale!

 

K&N Or Motorcraft!

Your Pony Deserves Nothing Less!

that is what i went with, i bought the K&N and put it in, too bad i bought the JLT but hey the car did feel alot better

 

33-2298 is the number for the K&N drop in filter, it is the same for V6 and GT's, autozone or advance auto parts can and should be able to order one for you

 

Only place I could get one was from the dealer

 

Something to remember on a K&N filter, they do not filter as much dirt and dust as a stock filter. They do flow air easier, but at the expense of very small particle filtration. Basically it allows more dirt into your engine, which dirties the oil faster, which creates more wear on the internals. Just something to be aware of...

 

Purolator makes one for the Stang...about $10 cheaper...I believe that the Motorcraft OEM filter is around $40...you will also need to change out the cabin air filter once a year...I couldn't find a non OEM cabin air filter...that's not exactly cheap either. K&N may let in a bit more air and a possible increase of 2-3 more HP...but when it's time to re-oil it...be careful, most folks either under oil it or over oil it...if you under oil the filter...then it won't trap much dirt, if you over oil it, the excess oil will be sucked into your engine and it will coat the MAF (Mass Air Flow) sensor and cause all kinds of little troubles...

 

thank god i am getting it off the car sometime next week

They have the factory cabin air filter (FP53 - this is the motorcraft # my parts dealer gave me) and the factory engine air filter, along with the aftermarket filters.

 

Merry Christmas to all and thanks for all the info. It is well taken.

 

Hey Scarpi,
Merry Xmas to you also. If you are interested I have an S&B filter that came with my CDC Shaker Hood kit that I am not every going to use. If you want to send me the $ for shipping only it's yours. It is designed to fit the stock airbox and is the same thing as a K&N. Just dorp me a PM and it's yours. Merry Xmas!!

I totally agree. I will not buy a CAI kit because they all use K&N style filters.

 

I've been running K&N's on every vehicle I own or have owned for the last 15 years and a few of those I put 150,000 mile on! and they all have ran beautifully! .. change your oil every 3500 to 5000 miles and you wont have any problems! as long as they keep the bugs and birds out thats all I'm worried about!...

 

I've seen used oil analysis results of engines that used K&N filters with minimal Silicon content, but there's also the oil that starts to come off the filter media and damages MAF sensor elements. K&N did a video interview saying otherwise, but there are numerous reports of fresh K&N filters or K&N style filters causing MAF contamination out of the box.

Until I see the bulk of the insurgent killing machines out in the desert using K&N filters, I will stick with paper.

 

Your scaring me! When I start using my Stang in the desert as a insurgent killing machine I'll use paper! but until then the K&N works fine!

 

well you will be missing out because all superchargers, turbos, and CAI's use a K&N style filter, even the roush chargers recommend a higher flowing filter then stock

 

It is not a big deal. I know paper filters work better for filtration. If you want to talk about flow, then consider that the 2003-2004 Mercury Marauders use 80mm MAFs with paper panel filters straight out of the factory. They can run 12 seconds in the 1/4 mile using the stock airbox, stock MAF, with the factory stock paper panel filter and a Trilogy blower kit. In fact, the stock Marauder airbox + MAF adds about 15-20 hp on the regular N/A 4.6 2V Crown Vic. Ford did something similar w/ the 2004-up Police cars. They used a straighter inlet tube with a larger 80mm MAF to achieve 250 hp versus 239 hp for the non-Police 04-up Panthers.

I think it is just more profitable to make/sell CAI kits with fancy cotton gauze filters for the performance-oriented community, rather than develop a “boring” low-restriction airbox/lid and use a larger MAF with an air transfer function suited for more horsepower.

The biggest restriction that I can see in the S-197 GT intake is the airbox lid and stock MAF sensor. The air transfer function for the stock 07 GT MAF is almost identical to the 70mm factory MAF on my 2000 Crown Vic (pegs out at a meager 39 #/min). I’d expect gains of 10-15 hp on the GT just using a larger MAF and an optimized airbox/lid with the stock paper panel filter.

Here is a chart for your viewing pleasure!

The aftermarket S-197 GT CAIs that produce significant hp/torque gains have air transfer functions similar to that of the 03 Marauder MAF (like the C&L CAI kit). That's also why CAI kits that require the stock factory MAF only produce minimal tq/hp gains. While the filter and airbox are changed in the equation, the biggest restriction remains: the factory MAF.
