Whats the deal with this intake? What makes this different from the stock ones.Roush Intake

 

That looks just like the stock one to me!

 

i might be wrong, but i thought i think it has a cone filter. that box you see is just a heat shield.

 

i have one and a few other people do to
not bad for the price just replace the cheap paper cone filter

Probably not going to do much for you but look fancy.

 

It has no silencing and the fiberglass box has a very large opening to the high pressure area in the front of the truck. By appearances, it should also do a good job of shielding the intake from hot underhood air - probably as good as the stock filter box can. (Many so-called "cold air intakes", especially the cheapies, are exactly the opposite, with little or no shielding to prevent the filter from sucking hot air from the engine compartment.)

BTW, this is not a Roush-designed part. It was originally manufactured by SLP for the 2002/3 limited production Ranger Thunderbolt conversion. Roush bought the leftover parts inventory when production stopped, slapped their labels on the boxes and listed them on their website for large dollars. Later, the surplus was resold to Hillbank Motorsports who sold them primarily on eBay for a fraction of the Roush price. Indications are that ap_liquidators (the current eBay seller) is just another name for Hillbank.

At the time, SLP claimed that their intake and exhaust together made a 15 HP increase over a stock 4.0L (but somewhat less on a 3.0L). When I installed the intake alone on a 4.0L, the WOT intake roar was louder at all speeds and, FWIW, the butt dyno said that acceleration felt a little stronger, especially at highway speeds. I have no data to back that up.

Anyway, it is cheap compared to other intakes and easy enough to install but does require that 2 holes be drilled in the core support for the mounting tabs.

The original paper filter element (P/N P549405-016-190) was made by Donaldson and may no longer be available as a replacement. That shouldn't be a problem though - just swap in a universal nanofiber filter or oiled gauze filter when the time comes. Someone else did research on this and came up with K&N part number #RC-4650. Of course, the total price then roughly doubles which obviously makes it less attractive...

 

Correct but you will have to mod the K&N filter because the unit incuding the rubber flange is too long for the intake box
A easy fix with a sharp utility knife just take about a 1" off the bottom rubber flange
At least thats what i did

On a side note if any one wonts my original paper filter just pay shipping

 

Thanks guys. So is it a good intake on the cheaper end of the spectrum? Does anyother K&N fit it?

 

What are you trying to accomplish with this intake?

 

the reason i like it is the heat shield

there where a few other elements from K&N that will fit too
check them out here

Maybe a slight increase in gas Mileage, but really just better airflow without being to flashy



BTW what size filter does it take?

 

anyother info on this intake? to those who have this intake would you reconmend it

 

does an one have the roush cold air intake ?

 

Back from the dead!!!!!!!

Since Donaldson no longer makes the paper filter, what are my options for a paper cone filter? I would rather not go with a K&N if I don't have to but it is looking that way.

I went to Autozone and went through all their larger boxes and some guy comes over and said "woah, woah we can look that part number up for you." I replied back "ok" and we went back to the computer. He asked what make model it was from, "I told him it was from a 2003 Ford Ranger SLP." He said I'm not showing a model SLP, and he asked what engine, 3.0. He went over and got the panel filter and said this is what you need. I said well this is what came off of it...lol he said well then we don't have your part...

I tried to explain to him what an SLP was but he didn't care to learn.

I figured you guys might know...

 

Grab measurements off the filter.....like inlet ID, height, width on the bottom of the element, width at top of element. .......and get an AEM Dryflo.

Also...I felt the most "power" with the stock tube and Thunderbolt/Roush/SLP box. Cool air shielded from the engine heat. I still want to get a custom tube mandrel bent intake tube, so i can run the roush box and a nice uncrushable tube. Would be killer.

 

thats what i did for the k&n replacement





i say the same thing no matter what others say


now that would be cool if you do let me know i may have you make me one too

 

I tried it with my K&N tube......and to make it work, I would need to cut about 1.5" off the tube. And I didn't want to do that. I have yet to try it out on my MAC tube. I wanted to make a AEM/Roush/K&N hybrid. Still might just take the hack saw to them.

Of course....this is on a 4.0 using a 3.0 Roush intake. lol.

 

I would need to get the 2.5" Dryflow Air Filter Short Neck 5" Element 21-201DK.

My concern is that it's only 5" in length compared the the K&Ns 7" length. Do you think it will matter that much?

On the other hand the Donaldson is a weird looking filter anyways.

 

i was going to try the same thing with my old k&n tube but rather than cutting it up i sold it
ya i finaly threw out the paper filter after trying to give it away for a year lol

as in the size of the dry flow i dont see a problem with that size due to the old paper one you got with the kit originaly

 

I got the K&N air filter on and wow it has made a huge difference. The old Donaldson filter was on it's last leg. I could shake the dirt out of it but it didn't have that many miles on it. Hrmph. It didn't look like that great of a filter to begin with but the K&N fills the intake up nicely now.
