Here is a picture of the filter, the basic problem is the hose clamp keeps sliding off, at first is was assumed a oil issue from the factory oiling. But after cleaning it and try to keep the clamp from sliding off for 30mins I've concluded it's a poor design. Has anyone had this problem? The old filters were a single filter with just one hose clamp the new and improved! filter has two clamps and is a pain
If I were you, I'd get a K&N cone filter that fits the end of the pipe and ditch that cheap foam thing.
Yep. I ditched mine as well, picked up a 3.15" ID K&N for my big maf there's plenty of different styles and sizes to choose from. Then sell that thing on nasioc.
This filter made the most power on our Dyno test. It is not a bad filter at all. Throw that "foam crap" talk in the garbage, its a great filter. Break clean and get everything off the filter clamp section. Have someone hold the clamp up while you tighten it down. Mine was doing the same thing but I got it with someone holding it. Great filter, don't toss it.
Actually, Perrin = Fitment issues. All day, every day. And Jeff Perrin thinks he farts out gold dust. My favorite example was the GT35R kit. Dream had fitment issues, I had fitment issues. At the time Dream bought the kit it was 3300.00 bucks or something. Then Ultimate Racing and a few others started selling better fitting kits for around 4000 dollars or more. So, out of nowhere, Perrin jacks the price of their GT35R kit up over 4000 dollars. Same ****ty fitting pipes, same parts, but somehow, the price went up about 700 bucks. Like Ben said, that filter falls apart. Most other companies sell a metal backed cloth screen filter that, when properly oiled, will last as long as your car does.
The only way to really know is to test each of them on a flow bench. That would be concrete data on how restrictive each would be.
the old perrin stuff fits like ass. the new perrin stuff surprisingly fits pretty well. at least my v2 fmic and v2 short ram do anyway. its not a perfect fit, but leaps and bounds better than the previous gen ones ive installed and worked on. anyway, michael, i have the same filter and had the same issue. the key is to not over tighten it. just dry the mating surfaces then slowly tighten it while holding the clamp straight. it doesnt need to be torqued down hard, just enough to keep the 2 pieces from sliding apart.
I got a big maf because my old perrin filter finally fell apart due to my crappy install job getting things to fit. my fault. I recieved this filter as well and was not very satisfied with the rubber reducer in the other rubber hole. CLAMP DOES NOT STAY PUT! I tried cleaning it and did a lot. I did finally figure out a fix however. I cut pieces of sandpaper as wide as the clamp and now it stays somewhat. lol Shouldnt have to rig somethiong like this up this way but so far its working. I say go to a design like k&N and not need a reducer. " I did not install the BIG MAF yet (no money for tune and wanted a few extra things b4 new tune) but you still need the reducer for that. ONE HOLE (sorry dont mean to make that sound wrong) would be better and no reducers! K&N figured it out..
As Sheen said, the air filter only needs to be tight enough to not fall off. It's not like there is 20psi behind it.
thats the other thing i didnt even try to tighten it that hard and still after being cleaned as the car was running it would still slide off
Hmmmmm. A little spray adhesive to keep it from going anywhere, and still get it off? That sounds quite annoying.
Oooo Ooo, me too. I'd also be interested to see the filtration differences. Even if an intake flows more, if it doesn't filter worth ****, that is going to be a problem.
Who cares about how it flows? I bet you'd get even more whp to redline with no filter. It's there to trap particles from ENTERING YOUR ENGINE. Get something that won't fall apart.
Perrin filter bits have got to be good for extra WHP. It's a Perrin, ferchrissakes. Just their stickers will give you 10whp. :laugh:
In a round about way, that's where I was headed. I'm sure if you did 3 pulls back to back using different filters, you'd probably find a fluctuation somewhere. Which filter it would favor is anyone's guess. But personally, the device that keeps dirt and debris from entering my car is going to be durable and reliable. It will also fit properly and seal properly without me ****ing around with stuff that wasn't in the box.
More then 10whp Brian, Plus the filter ads like $1000 resale value because the car is modified! My old filter was a Red Perrin Filter that came with the Big MAF intake kit it made 310whp and the new black filter make 300's flat. As far a clamping the hose clamp just lightly tightening works the best. Don't by a Perrin Filter (fitment should have never been an issue!) go with K&N for best fitment
I think this is what Adam was talking about, it doesn't test the filtration of the filters tested however it does have dyno graphs for each filter Air Filter Shootout On a side note, I run a Fujita on my DSM and it is a very high quality filter at about the same price as a K&N
Why all the Perrin hate? I can't say that I have used one of their intakes...but their exhausts are very good.
That whole air filter 'test' smells. First, I can tell you with 100% confidence, that over 3 runs you're going to find a spread of about 5hp or more. I would have AVERAGED the results of the 3 runs and pitted the average readings against eachother. I don't think you would have found a 10hp spread at that point. But regardless, my point wasn't that it did or didn't flow better, my point was that the filter itself is flimsy, and cheap, and suffers from the same "fitment AIDS" that every other Perrin product has (or used to have). Great, so K&N's bigger filter made 7hp less, I'd much rather give up this mystical 7hp and use the K&N than use the Perrin filter, have it fit like ****, and have it fragment or disintegrate while I'm driving.
A good filter is what I'm after not 10 whp on the dyno, I can't tell the differnce anyways. Its was fun to see what it showed on the dyon when Ron at RS was doing some pulls with my new 20G setup. -Clean air for my subies makes it happy for long time-
