This is a metal intake from the MAF to the throttle body. Also a filter at the intake to the MAF.

This is Junk. I received a system that would not fit and had to be shortened by 4" at both ends and the two hose fitting were in the wrong location. Marked up the intake to be shortened and hose fittings to be relocated. When I received the intake back from Weapon-R they had made the corrections except the hose fitting for the air intake to cool the water in the throttle body was located directly infront of the fitting, it had been marked to the outside of the bend. Also, where one of the fittings were removed a hole was left and when they drilled the pipe for the 3/4" fitting they also drilled through the internal pipe which defeats their design. Finally Weapon-R agreed to move the fitting but instead sent another intake completely different from the one sent originally (shortened and the hose fittings relocated) and I could make it fit except the 1/8" hose fitting for the cam cover was located on top of the intake pipe. This prevented closing the hood with the hos! e on the fitting. Weapon-R said this was the production model and the hood would close. Weapon-R would do nothing else.

Stay away from Weapon-R intake products. It appears they try to make a general intake fit all cars. They got me for $213.15. Definitely not worth the cost!

Product came in good packaging, and man was it a beauty. Aluminum looked flawless, and the filter was a very interesting design. Came with everything you need to swap out the old plastic pipes. Also came with a plastic head shield and some filter cleaner.

Since i had researched this product before i bought it (and read what was said here closely), i thought this intake would be the way to go. though im not sure if it was just me, or maybe i was just sent some of the wrong or faulty pieces, i had a very difficult time installing this, even w/ the help of my father, whos a professional mechanic. the instructions were very vague, and the connectors didnt seem to be the correct size. i had to actually put the stock rubber seal that connects to your throttle body in the new one so it was the right size. it took a lot of little mods like that to make it fit and work. the worst part was the seal that connects your AFM to the new pipe. the pipe was cut at an angle, and the seal would refuse to stay on, had to sand the first inch of the pipe to get some grip. took 3 hours to get it all right. Now heres the good part, true to their word, this intake does work very well. and the sound of it, its like having a brand new muffler. you get a really deep growling sound when you hit around 3000 rpm. i wouldnt say i have a 10-14 boost like they claim. probably more like 5-10, but still a noticeable increase in the pull.

overall, i am happy w/ this. once you have it on, it does do its job very well. and it might have just been some faulty parts that were sent to me. installation was a bitch, but looks and performance are a beauty.

It is a metal tube that takes place of your stock plastic air intake. The new tube is smooth and alot larger, it connects from the throttle body to the AFM (Air Flow Meter) then it goes to the dragon filter which really looks good.

This was my first performance product i'd ever put on my car and i could really tell it. First of all, the sound now was really low and nice sounding. Then when I drove it down the street you could feel the power that came with it.I'm guessing 10 - 14 HP.

I recomend this product. the only problem was that i had to take out my strut bar.

Foam air filter w/ heat-resistant plastic assembly. Inner frame has air diffusers all around, and an upper velocity stack and a lower velocity stack. Foam is wet-type.

Good air filter. Sounds nice, easy to stick onto the MAF Sensor. only problem is heat, but thats because i didnt fabricate a heat shield.

I like this air filter. the assembly/skeleton IS plastic, so it may not be very take care in where you put it. Worth the moolah.

This is a complete intake designed to replace air box and tubing.

I've had the product on for 2 weeks now, so I'm still having a difficult time determining if I like it. The Intake feels like it does give more horsepower in the upper RPM band. This may be due to the fact I just added Underdrive Pulleys on the car a week earlier. I'll write back if there are any major problems that come up.

While the removal of the stock intake is quite simple, the fitment of the new intake is not as easy. Better directions with pictures could have been provided. With a little bit of time any shade tree mechanic can do this.

WeaponR intake is make from aluminum tubing with a J pattern (more or less). Also, comes with a high flow filter not K&N.

Well, how can I look at this objectively? I don't know if this is this case with all aftermarket supplier, but their Costumer (WeaponR) is non-existent. The product arrived through Darkside Motoring, a distributor in Chatsworth C.A. First problem, some parts were missing. I did my best (3 hours) to compensate for the lost parts, all to no avail. The tubing is not even close to what the stock tubing. I don't understand why they can't just look at both and design accordingly. The filter element hangs way to close to the exhaust manifold; I have a feeling if I would have left it for longer that the 4 hours, I would have damaged (if not melted) the filter element.

Although the car pulled a bit better after 4k RPM, (maybe 4 HP gain) I question the protection this filter offers against tiny particles. The whole product cost $119.00 through Darkside, but I'm looking to get a refund for this product (or lack of it). Don't buy it, avoid the headache. WeaponR Rep claimed 12-14 HP gains.........LOL......NO WAY!!! maybe 5.

This is a cone filter that replaces the entire airbox assembly. The entire unit is black and is constructed very well. The filter material is foam and is protected by a metal screen. The filter housing is made of rubber and has an air horn molded in to help direct air to the airmass sensor.

Installation on a 1993 1.6L

First you remove the stock airbox.
Then you bolt on the airmass sensor adapter.
The airmass sensor has a rectangular inlet, but the filter has a circular outlet.
Make sure you get a circular to rectangular adapter or the filter is useless.
Once the adapter is on, a hose clamp secures the filter.
Install time is about 30 minutes.


There was no support brace provided with the filter. By removing the airbox, there is nothing to support the airmass sensor and the cone filter. You will need to fabricate your own support brace for the airmass sensor or the filter will melt on the exhaust heatshield.

Performance evaluation:

I cannot feel any power increase, but would have to guess it is good for a few horsepower because the stock box is so restrictive. There is nothing wrong with the design of the filter. Mazda's rectangular airmass sensor is what is holding up the air. An airhorn for the airmass sensor would help, but I have never heard of anyone making such a thing.

Although power increase is negligible, I can definitely hear a difference. This cone gives the engine a deep growling noise from 3500 to 5000 rpm. People have asked if I changed my exhaust (I haven't) because it sounds so different. The filter and adapter cost me $120 which is cheap compared to any other filter system.  If you want to change the sound of your engine, this is a good buy. If you want a noticeable boost in power, you would be better off buying something else.
