Can anyone give me any information on their experience (or whatever) with the K&N drop in replacement filter? How much does it cost? How well does it work? How much of a horsepower gain does it give? Or can I use two of their cone filters in the stock air box? I am mainly interested in the drop in replacement, or whatever works best. Any feedback would be greatly appriciated. Thanks.

 

I would definitely go with the cone intake. No you can;t drop in 2 cones into the stock box. the cone will replace the box itself and give you from 5-10 HP probably. The drop in will maybe give you 3-5 i guess. I'm sure you could custom make a dual cone intake system if you like. Or make a cold air box to make the intake air temps lower. Well there ya go.

 

Where do u get those round filters?

 

I would like to know where you get the cone filters as well. Anyone know????

anyplace that sells the k&n drop ins should have the cones. thier called a "tapered" cone. they have really big ones. just get the one of the size you need in length. and whatever inlet size you need.

 

Does anyone know what size the pettit intake system uses? Or does anyone recommend a different size? Thanks

I don't even have a 3rd gen so I don't know. Contact Pettit & ask.

 

I installed mine yesterday paired with a Racing Beat Cold Air Inlet Duct and it is pretty good. I didn't have enough money for a good cold box so I went and got this combo for 160 bucks (100 for the duct/60 for the filter at racingbeat.com) and change (1.50 for degreaser and 1.50 for a tube of black silicone adhesive). There's some cutting involved for the Cold Air Inlet duct but it was so easy to figure out. They had installation pictures at Mazdatrix.com. The hardest time I had was removing and re-installing the air hoses. I broke one in the process because it was dry rotted. No big deal.

As far as performance....It was a big difference over stock. I would say it breathed better. I never knew how many horses my seven had to begin with but it sure hauled major *** after I test drove it.

Hahaha...funny thing happened while I was test driving. I forgot to hook up one of the brake hoses (I removed this hose to get to the one I broke) back in its place. It revved up and down 2k to 3k and so forth. I decided to drive the car around the block. In the middle of a declining road I realized I didn't have any brakes. That worried the holy crap out of me and I thought that messed this car up big time. Yes.. I made it hope slowly but surely. I popped up the hood, checked out my ABS relays (for some reason), then I looked over my master cylinder followed the line/hose directly to the hose that I took off. Whewwww! I put it back, cranked up the beast, revved perfect, pulled off the drive way and off to the sunset...with a big grin (of course).

Sorry for the essay but K&N filter is good in my opinion.

You paid $160 for the drop in filter or the cone one? You can get the cone K&N from discount auto parts for around $40-50 which will give you better performance than the drop in. But you noticed a difference just with the drop in huh? Thats good, when I get my cone should be able to tell then.

 

I paid 60 bucks for the drop in filters and 100 bucks for the Cold Air Duct.

I have the drop in K&N filter it gives around 5 or less as our another pal said.

I don´t recomend the cone filters, not because the cone, is because the heat that your engine will swallow. Those cold intakes with cone filters are not cold enough, in his page, Steve Ciriani has a discussion about this point. www.scuderiaciriani.com.

Once you install the drop in K&N filter, you can do the Poor man stock intake box modification that is explained in the Rob Robinette´s web page - I don´t remember the address right now-. That´s what I am going to do.

good luck.

 

Yea, I am going to do the cone & cold air box for my car. I am also going to have another fresh air supply from the front spoiler. I plan on not gettin very much warm air in there at all & hope to see 10RWHP once I am all set in done with my intake system.

 

You loose thepoint.. I need the cones because you cannot use the factory box with a front mounted intercooler!

 

You can get the cones from anywhere. Discount Auto or Auto Zone, where ever. Be sure to get K&N brand. Come with a 1,000,000 mile warranty

 

Check out the universal filters and crankcase vent filters if you have an air pump:
http://www.knfilters.com/

Here are some K&N retailers. The Turbonetics link also gives approximate HP ratings.

If you know how to open your hood, operate a screwdriver, and operate a tapemeasure, then you can figure out what size you need.

 

If I can not use the stock air box because another intercooler, I would like to use the M2 intake, is very famous but very expensive, around $500. It gives TRUE cold air. Is made with carbon fiber.

M2 web page: www.m2performance.com

 

If you have a big-*** intercooler, then it's not a huge deal sucking in hot air from the filter. The turbo compresses it and heats it anyway. The aforementioned big-*** intercooler will make that hot air icy cold for your 13B to ingest :p

I'm paraphrasing Chris at RP, but you get the point

 

Perfect!, if you have a BIG-*** intercooler, use the cone filter as intake, it will fit to you and to those pals that has big intercoolers, for the mortals like me with the stock intercooler, the more reasonable and healthy solution is to use a TRUE COLD air intake.

you can just call pettit and buy only the filters. theyre like 27 bux each.

 

KI-PE-IN100 TKT COLD AIR INDUCTION SYSTEM
The TKT COLD AIR INDUCTION SYSTEM is by far the most advanced induction system available for third generation RX-7's. Outstanding design features include two big K&N lifetime filters (one for each turbo), a unique cold air duct which draws in cool outside air (rather than superheated engine compartment air), our unique EAM manifold which routes emission and accessories discharge to a third K&N filter (virtually eliminating turbulence from the main induction tract), thus maximizing intake velocity and flow. The complete kit bolts in the stock air box location in about 1 hour using basic hand tools and comes with fully illustrated instructions and all necessary hardware.




This is the system that I installed from Pettit, using not one, not two, but three K&N filters. We're talking Air Here!

The cost is $399.95

 

I couldn't agree more. I have it and I love it.

 

I would go with the cone filter as well or pick a good intake. The drop in is cheaper and better than stock though so what ever floats your boat.

 

Anyone know the size of the K&N filter for the air pump on a 2nd gen? Thanks.

 

you just get a small thing called a crankcase filter. its a universal size, really small.
