a few questions about evo mods.
first, yes i am new to the evo8 but not to motor building/tuning/fabrication,etc.
anyway, i just wondered why you guys dislike the aftermarket "cone filter" on stock evo's?
also, what spark plugs do you reccomend running on an evo that is mostly stock(just boost controller)?
is the "re-flash" idea good if i still want to retain my warranty and is it traceable if flashed back to stock?
thanks, I love this car!

Open element filters are okay, but a lot of guys think the benefit of the larger airlfow capacity is negated by the fact that it's not taking in cold air like the stock intake is designed to do. Intakes in general are harder to tune for because they can distrupt the MAF sensor. Personally, I've never had a problem with an aftermarket intake.
Spark plugs - you can either use the stock ones, NGK iridiums, or NGK BPR7ES's. The latter is the cheapest route, but you must change them every 5,000 miles or so.
As far as reflashing goes, I dont know for a fact if the dealership can detect whether or not the ECU has been tampered with, but as long as you flash it back to stock before visiting them, you'd be covered. I wouldn't worry about that. I've never heard of anyone having an issue with warranty work over an ECU flash.

I built my own heat sheild and 4" intake duct to my cone filter. After a hard 2 hour drive on a hot day, the filter is still cool to the touch. At most it may be slightly warm. Sometimes, it's actually cold. But the point is, it's the best of both worlds. More airflow, as well as cool airflow

well thanks for the responses. i appreciate it.
i have been reading a lot about cones messin with peoples full throttle and hesitation and whatnot. which is why i opted for a k&n drop in.
do any of you recommend a certain flash for a mildly modded evo over another? i am buying the tactrix cable from a local tuner for 85 and dont want to run just any old jokers flash ya know. is that jestr place the best one to go to for the flash?
thanks again guys!

well i decided to test this "myth" out about the cone filter giving people crap, and here is what i found:
with all things remaining the same( boost controller still set at 20-21 psi) i hooked up the cone adapter and cone filter and......
the car ran like garbage.
the turbo was louder and bov and such, but the boost response was crap and under full throttle........ it was hesitating and jerky and just very very weak.
so i put the stock airbox back on with the stock filter and all. and...
bam! back in business. immediate response, much much MUCH more hop/tq!
so in conclusion;
a cone filter with adapter on the stock setup with boost controller= weak *** power and crappy acceleration.
K&N drop in is the only way to go unless you go get tuned for the other option.
hope this helps others out.

listen, not all of us have 2+ hours to spend searching a topic for a mixed result final. some of us have other things to do. so thats why its best to go out and get the info that someone couldnt simply type in a response.
thats why the "search" feature didnt work for me,
and thats why i did the test and posted 100% confirmed results so that if anyone did search this, they would get a conclusion and not a "problem with possible solutions that was never solved" thread.
