I have been very happy with my J's intake, but thought it could use a better filter. K&N part number RT-4610 fits perfectly (and it is has the titanium end cap ).

No butt dyno results to report, but I do have images...

 

looks better than the one j's supplies.

 

i love my k&n filter as well.....you can also get the carbon fiber end cap as well....whoooo whoooo

 

5 thumbs up

thats 4.99 for the car and 0.1 for the filter

 

k&n . . .

Is this because you haven't had much time to drive it around, or that it didn't do a damn thing for ya?

It is because a butt dyno doesn't tell anybody jack, but I know this filter is a huge improvement over the one that came with the intake...

 

Looks much better Jonathan

 

So you're telling me that the intake that came with the J's is not good? Should I replace it too?

The filter on the J's intake did seem a little cheap to me in both construction and appearance. I wanted something that was higher quality that would also flow better. This filter is a perfect fit and just wanted to let other J's intake owners the part # is they were interested.

J's intake + K&N Filter =

 

I wanted to do that one too but let go of my j's intake before I had the chance. Much much better.

 

looks good and performs well....the best of both worlds...

 

How much more did you have to fork out for the K&N filter? Still haveing any rubbing issues?

 

ooooh...nice

 

Ntot o get off the subject (thanks for the in for on which K&N fits), but doesn't ATS USA sell the J's intake with a K&N filter on it already?

 

I will have to post pics of mine too. I got the carbon fiber cap on the end of mine for some extra bling.

 

i would really really like to know what the diameter is on that filter... i'm curious to know if it will fit my set-up (not J's)!!!!!!!
if i could get you to measure it that would be great!!! thanx in advance!

Looks awesome!

 

Hey Bryan, measure your intake and then go here http://www.knfilters.com/universal/universal.htm and choose your poison.

Also, give this http://www.knfilters.com/facts.htm a read. Some good info there about airfilters, most about K&N, but still pretty good.

Look at this about getting the right sized filter: http://www.knfilters.com/facts.htm#SELECT

Filter Selection

If maximum horsepower is the objective, the size and shape of the air filter element is paramount.

Let's first consider shape. When fitting a conventional round filter on top of the engine, such as a carburetor, central fuel injection or throttle body fuel injection, we have found a large diameter, short filter will flow more air than a small diameter, tall filter. For example, a 10-inch diameter filter 2-inches tall will flow more air than a 5-inch diameter filter that is 4-inches tall. Where space permits, the height of the filter should be between 1/5 and 1/4 of its diameter.

The shape of the filter is less important if the application calls for a remote mounted filter, which includes many late model fuel injected models. Typically these vehicles will use a flat panel filter or a conical or cylindrical shaped filter with a rubber mounting flange designed to be mounted on the end of the inlet hose.

That brings us to size.

Use the formula below to compute the minimum size filter required for your particular application. The usable portion of the filter is called the EFFECTIVE FILTERING AREA which is determined by multiplying the diameter of the filter times Pi (3.1416) times the height of the air filter in inches, then subtracting .75-inch. We subtract .75-inch to compensate for the rubber seals on each end of the element and the filter material near them since very little air flows through this area.


A = effective filtering area
CID = cubic inch displacement
RPM = revolutions per minute at maximum power

Example: A 350 CID Chevy engine with a horsepower peak at 5,500 rpm.


If you are sizing a panel filter, multiply the width of the filter area (not the rubber seal) times its length. If you are sizing a round filter, use the following formula to determine the height of the filter.


A = effective filtering area
H = height
D = outside diameter of the filter
3.14 = pi
0.75 = the rubber end caps

Example:


Referencing the K&N catalog shows the proper filter for this application would be an E-1500 which is 3.5 inches tall. Keep in mind, this is the minimum size requirement. To extend the service interval and to provide an even greater volume of air to the engine, install the largest filter that will fit in the space allotted. If the space above the engine is restrictive, perhaps a remote filter arrangement could be used to gain space.

Off-road conditions require added filter area. A filter should be sized 1-1/2 to 2 times larger than normal for any conditions that could be considered severe. In this case, the E-1500 used in our example should be replaced by an E-1120 or an E-1150. For long distance off-road events, two double-size remote mounted filters would be best.

I hope you, or anyone finds that interesting.

 

Looks good

 

When I checked RT-4610 it says it has a chrome cap. Where did you purchase your filter?

I think their descriptions are just wrong.
I got mine here:
http://www.performanceproducts.com/

That part number is usually not stocked by most places, so it will take 2-3 weeks to get one.

 

WOW. that filter shows up as $80 !!! thats ALOT for a damn filter. not worth it in my opinion

That is why I bought it and you did not...
