K & N intake filter egg shape
Meat around 8:00 I now have an engine light :s
rotate it more upwards. When I checked fuel trims around that position, they were waaaay positive if I remember correctly. You probably exceeded +18.0% LTFT and set a CEL.
Yes, the metal pleate that connects the filter material should be positioned around 12:30 (and the K&N logo on the front will be upside-down).
I, personally, have it set up the complete opposite for looks
But I was able to tune my fuel trims to accomodate it that way. Not recommended unless you will be spending A LOT of time fine tuning the fuel trims.

Im tuned currently but obviously not for the typhoon, but i will be this weekend at our dyno day. So im not worried bout it, lol. Ill check the trims on the DH on the way home on mine

I can't seem to get my fuel trims below +13 with the K&N. They were at +2 with the stock intake. I've tried rotating the filter to almost every position and it doesn't seem to matter. I'm planning on getting a retune hopefully soon.
That is most likely why it skewed so much. What I've read and experienced myself is, installing the Typhoon intake on a completely stock balt doesn't skew the trims so much when the filter is positioned to 12:30 (The metal pleat in the filter). BUT, if you've been tuned with the stock box or even another intake, rotating the filter will do nothing to help your trims. It's been tuned specifically for your previous setup and will need to be retuned again.
Again, this is just what I've experienced and read.
I asked Vince @Trifecta about this and he claims I shouldn't need a re-tune unless I feel it not running right. I have no way to check my fuel trims so I guess I won't know unless I feel it running rough.
You got the intake after you were initially tuned by Trifecta?

It probably won't hurt anything, but I don't like to trust "probably".

And again, that's my thinking.
Watched mine lastnight as well as this morning, currently LTFT's are sittin around +8.6 give or take. Dont seem to be running bad at all
. Ive only got one complaint about this setup, and thats i cant keep my foot outta her!!!

What are you using to watch them? Personally, (and this is just my opinion again), I wouldn't want my LTFT's to be outside of +/-4. But I am a bit of an **** OCD perfectionist and I keep mine within +/-1.8 lol.
dont mean to thread jack but, i have a zzp charge pipe and catless downpipe. i am wanting to purchase the K&N SRI but dont know how much it will effect my ltft/stft with out gettin a tune. i guess my ? is, is this a good idea to do or not???
you'll be fine it you position the filter the right way
