JLT or K+N Cold Air Intake

[Skiordie53]

Anyone know the pros and cons to each of these products besides price, would like to get one to start modding my 04 but cant decide which is better.

[Rider90]

both are just as good as the next. I got the K&N because, well.....I don't know. It seemed like a good idea at the time? I've heard nothing but good things about JLT but do a search and see for yourself.

[DEFYANT]

I got the JLT. This was the correct choice for ME. The answer you seek is here, search around, you'll find it. That is how I decided. I cant tell you what to do.

[Directedby]

I got the JLT but I prefer the look of the K&N. But the JLT is half the price.

I guess they perform the same?

[Rkammer]

I purchased the K&N even though it cost more than several of the other brands. I liked it because of the great appearance and super easy installation and fit. If you want functionality and would like to save some money you might want to consider several of the less costly kits. Any of the various brands will give you about the same performance gains IMO. :)

Just bought and installed the JLT intake and let me say the difference is night and day. The car has a meaner sound when your on it and it feels more responsive. Plus the quality of the product is top notch. Can't beat the price either.

I have the K&N. Did a dyno run before I got my supercharger and the K&N gave me about 7 hp. With the supercharger it gave me an additional 22 hp. I love the sound with and without the supercharger at WOT. I do like the look of the JLT since you can get in many colors. The choice is up to you on what you looking for.

Ilike the K&N kit. Several of our S. Fla members have it and love it. In fact there is an ad on Ebay motors for a kit for $239.95 buy it now + shipping.

I got my K&N on E-Bay and was very happy with the service-- the seller there is Exotictruck-car in Miami. Florida sales tax , plus $15 flat shipping to the above.

I bought my K&N set up from Alternative Auto ( check the vendors forum ) at the same time I bought the SCT tuner.

I like them both.
Your car.... your choice.

[Shaft333]

Are the JLT kits the ones that some have found to dig a bit into the hood liner?

I know for some, that's no big deal. But it'd stop me from buying one.

[Macon Marauder]

I own both! I have a JLT - and I also have a K&N on the Mustang GT. :) IMO you can't wrong with either one. If cost is a factor then go with JLT. I have no qualms recommending them (him?).

In fact, if I had known about JLT before, I probably would have bought one for the 'Stang as well and saved some money.

I have the JLT but I wish I would have gotten the PHP Kit from Dennis Reinhart, the JLT really messed up my air/fuel, but it is ok now thanks to an awesome SCT tune by Dennis.

Check out my review in the reviews section.

[valleyman]

I have the JLT and have had no problems of any kind. Would buy another in a heartbeat. Excellent bang for the buck. :twocents:

[txmarauder]

Very good ?. I have a s/c MM and looking for a intake setup as well. Looking at all 3 kits and searching members performance experiences, so far i have come to the conclusion that according to Dennis' site the php pictured is just a air box assy. with filter for around 250.00. Tests done on some air boxes ( not the php that i know of) have shown results of less air entering the filter because of the amount of open space around the filter. And some people have had problems with drivability, which maybe this php is so good that it requires a retune, but i doubt it. The k&n looks like the cleanest setup. One tube from t/b to maf, plastic intake tube to disapate heat. But a whopping 240 bucks for a tube, a filter, 2 pieces of hose and four clamps and a very basic heat shield with a weatherstrip seal all the way around ( which the only place it seals is on top to the hood 8-10 inches if you are lucky). Then there is the jlt, depending on where you get it will cost you 120 without a heat shield or 140 with a heat shield. But the system looks kind of chopped up by looking at it, too bulky of hoses connecting the intake tube. And if the tube is metal and above the header you would think it would add unwanted heat to the intake air. Well in my opinion the best looking kit is K&N, but the best in my opinion as far as hp to $ is jlt. For myself I think i will just wait for now and tinker with ideas to design my own setup, and make it a REAL COLD AIR KIT.JMO no bashing intended (everything in this world can be improved upon).

[BruteForce]

...if the [JLT] tube is metal...

Tube is thick PVC painted OEM color(s). You really need to see one of these in person to appreciate it.

[txmarauder]

Plastic, that is better, helps disapate the heat. The only one i have seen so far in person was a k&n, which looked pretty good. Just alot of money.

True, the K&N costs more, but then they spent a considerable amount of time and effort to design it to specifically fit the Marauder. I've had no problems with codes, no A/F adjustment needed, no additinal tuning needed, no problems with air leaks at the MAF, no rubbing on the hood insulator, the mounting brackets are still doing their jobs. It's a great product from a recognised name in the high performance aftermarket.

That kind of sums it up for me too and are the same reasons I chose the K&N.

Hey! This exactly describes my experience with the JLT unit!

[Cobra25]

I have the JLT and have had no problems of any kind. Would buy another in a heartbeat. Excellent bang for the buck. :twocents: I purchased the K&N , because I liked the way it fit's & looks. Both K&N & JLT do the same thing & work the same. It boil's down to personal preference.

[MarauderMarc]

I purchased the K&N for my car. I personally have never seen the JLT, but I chose the K&N because of years of proven performance. They were the first company I heard of and have used them ever since. My opinion for you is this...if you dont have a tight budget, and/or prefer a more stock looking engine then go with the K&N. If you are on a budget and/or you want to build up a color schemed engine compartment (hoses, valve covers, ect.) then go with the JLT. Just a quick note, after I installed the K&N, which was very easy, I took my car to the dyno and I gained 16.3rwhp. K&N claims 17.something so it was pretty close. My engine sounds meaner on acceleration and I have quicker throttle response. I couldnt be happier. Hope this helps......

Thanks for all the positive post guys.
Lots o'happy MM/JLT owners out there.:beer:

Here is another: PHP Box + JLT Tube = :D

[Big House]

Not crazy about the PHP box, I dremmeled my stock airbox to do the samething it does and it kinda looks stock at first glance, but go JLT. It scares people when I get on it, and dog gone...it works. With it and the other listed mods, ran a 14.43 in 90+ degree heat. And it looks good too.

I'm happy with my JLT, had no problems installing it and it's run fine for over 10,000 miles. Just my :twocents:

[MikesMerc]

After wieghing all the pros and cons of each kit (looks, fit, price, and performance) I went with the JLT kit. I've seen up close and personal both kits as well as seen performance numbers.

Looks:

IMO the JLT kit looks ALOT better than the K&N kit. The K&N looks "plastic" with the flat black molded plastic tube, while the JLT looks sharper with a nice painted tube with choice of color. The JLT has more *bling* in my opinion.


Fit:

Both seem to fit the marauder application great. I will give the smallest edge to the K&N kit as fitment is perfect while the JLT needs a tiny bit of work to get it not to rub on the hood liner.


Performance:

Tie. I've seen the dyno results myself between both kits on both SC and NA applications. They yield similar results.


Price:

JLT hands down.

[Smokie]

There is a 3rd choice: POST#4 (http://www.mercurymarauder.net/forums/showthread.php?t=19535)

[Fourth Horseman]

Didn't have the advantage of seeing any of these kits in person (no Marauders near me, sadly). Strongly considered the JLT kit, but ended up going with the K&N. My reasoning was that the heat shield looked more functional on the K&N than the JLT. Don't know if that's true or not, but just based on looks that's what I thought.

In any event, we've had enough members with positive results from all of the listed options that I don't really think you can go wrong with any of them.

[QWK SVT]

I have the JLT, and really like it. I also have a K&N FIPK on the Lightning. They both work well, and don't think you can go wrong.

Either way, the car will sound better (more growl) and feel stronger. Put to the test, the JLT showed a gain for me, too. I performed before / after measured 0-60 tests, to validate the increases that this kit provides. Same day difference averaged to about 0.3 seconds (0-60)

Pick the one you think fits YOU best - whihc looks better to you, and decide if cost is an issue. You'll get one of the kits out there, and will be happy :)

I have question. Does the JLT have to be cleaned and oiled every so often as the K&N does? I know one person that has a Pro-M and it cleans with soap and water and does not need oil.

In doing my research I saw that there is a "recharge" kit for those filters from the filter manufacturer, just as is there is for the K&N filters. Don't know if it included oil or not, but I'd think so, otherwise it's just an expensive soap kit. :)
