CBRD,

In an earlier post you mentioned you somewhat know why or have a theory on why this filter works better or the other ones don't. Could I take a shot at it and perhaps get your feedback? Something that always bothered me about these cone filters is the fact that the "straight" path to the maf sensor (or intake tube) is completely blocked off. Leaving the air to come from nowhere but all the sides of the filter. In which case, the air that comes through needs to make a sharp turn before going through the maf. And I am sure this creates lots of undirected turbulence. (pardon my terminology) To me, this would create erratic readings. One thing I noticed about the perrin is that its a completely open element all the way around in which air sucked through the center could go straight through the maf and create a better reading. I noticed that alot of intakes arent like that, except the HKS suction looks like it is, and I like the fact that the filter is replaceable every 5k, which would keep me in check instead of having to oil a filter all the time. <---yes a run-on sentence. Anyhow, I may have not read every single post on here, but did you do a head to head test on the perrin vs. the HKS suction? Thanks for any info.

 

i never tested the HKS, we have rarely a single client that uses them.

You are correct on your thoughts of why it works... there is also an internal screen in the perrin filter and the cut's in the screen angle inward toward the maf... also very nice..

plain and simple... it just works.

we use it with the BR mini batt. and uicp and we only have to trim about 3/4" off.

the other thing you can do is redrill the two mounting holes... that works well also.

I am assuming that it is a 3" opening for the turbo inlet?

 

Did you dyno this with just the filter? If not how much do you think just the filter will make? I have an ets intake and don't want to buy anthoner intake pipe but the filter I wouldn't mind replacing.

 

When i installed mine it leaned out the air/fuel mixture and boost went up. So it obviously flows more air. Here it is installed

would switching to this filter from a vibrant filter warrent a new tune?

 

Chad, did you ever get around to doing a dyno with the Perrin intake on a bone stock Evo to see the results? You mentioned a couple of times that you were looking to do that.

TIA

 

I purchased the Perrin intake and got it in. Everything looks great. One thing though, that bothered me, and many other companies do this as well, so its not a flame towards Perrin. But, why do all these manufacturers insist on using just regular nuts (in this case for the maf to heat shield) instead of locking nuts. With all the vibrations in the engine bay, one would think that these nuts over time would loosen. I mean, there werent even any lock washers included. Just a heads up to the vendors out there. I spend lots of money on parts for my GN and EVO and lots of times I just have to end up replacing the nuts with nylon locking nuts for piece of mind. I recommend it if you are purchasing this intake.

 

I never have problem with nuts loosen in my apexi intake.

 

Were the results of the Perrin intake on a stock IX ever posted?

 

i have the perrin intake system, i love it, i think i noticed a slight quicker spool an better top end IMO

 

i saw a post that perrin did on their new intake that they make 30 hp
