I ordered this unit yesterday. I will have a write up and review in a few days. This is what it looks like:

Very nice! I had an Injen on my WRX and loved it!

Injen Powerflow Review

Bought from http://www.ultimatetruck.com

Price: $357.20 and free shipping. AND a $20 off coupon on top of that. So I paid about $337.20 to my door.

Was drop shipped from Injen direct. (So I ordered out of state to save tax, then it still ships from CA anyway) No tracking number was given, although it arrived in 4 days, pretty good.

First picture, all the stock intake parts disassembled. This was about 10 mins work. One of the 3 stock airbox bolts is a tough reach, but a simple 10mm wrench can get it done, just takes some time.

after removing all the packing, I put all the parts back in the box for viewing:

One money shot of it installed, then I'll go into some detail:

(First off, move you MAF sensor/AIR sensor to your new Injen tube.)

From left to right... First you have the 3" hose coupler which attaches to your throttle body. It was a perfect fit, and did not need any stretching. The clamps are mid range, not cheap. They are very thick metal and very strong.

The middle is where some fitment issues came in. Maybe because this is a Pathfinder unit. The problem I encountered was the crankcase hose you see, coming into my Injen box. It just wasnt a straight fit, so the hose went under the engine cover a bit as you can see. after looking at the hard to read install document, the Pathfinder picture might have looked the same way, but its hard to tell.

Here is another view of the injen box. This is an integral part of the new MR tuned intake design. Before they added this, there was a loss of torque on the dyno. after, it shows gains in both hp and tq. Look very closely and see that bolt that is very close to the crankcase hose. I had a few mm space, but I removed that bolt just in case. It wasnt doing anything.

Moving to the airbox, the best piece. The 4" hose coupler was a perfect fit, and clamps were perfect also.

This bothered me a little bit, but I admit it feels pretty stable once installed. There is only ONE bolt holding the airbox, aside from the tube and clamps. the kit comes with a rubber isolation bushing which you can see under the bolt. This will stop vibrations from harming anything.

Finally, you do have an option of rigging some cold air source if you wanted. Injen might even sell a kit. The filter intake could have a hose added if desired:

And your hose might go into this fender hole like the stock one did:

I have not driven it yet, that will come later.

nice...i just got my k&n system today...very similar install from what i've gathered looking at the instructions. i'll be putting it into my x tomorrow and taking a test drive...can't wait to hear how it sounds

-john

damn its loud.... under that full throttle 2 gear kickdown, its deafening. little bit of drone in high gears/low rpm when u start stepping into it.

i dont hate it or anything, i have a lot more testing to do.

its way too loud for me.. after a freeway test im positive.

took it off. expensive lesson.

Bumping this up because I am jonsing for another air system now. I need to refresh on everything i didn't like about this system so i can talk myself out of buying another.

I do have a K&N drop-in but its out right now. I almost sold it.

dammit all my pics seem dead. ill work on it.

looks nice though man. i opted just to use the k&n drop in, way cheaper, not a crazy amount of power difference either, i mean its a big difference when comparing the two but as far as the dollar amount goes i mean, its not worth it to me to get an extra 10 hp or whatever it is for 300 bucks, lol. i will stick to my 33 dollar filter.

yea power gains typically arent huge with an intake on na engines, however, i fkn love the increase in throttle response! thats the reason i have intalled intakes on any of the cars/trucks ive owned
not to mention the lil bit it helps with the mpg being that the engine is ever so slightly more efficient

fixed all my pics again.. still have a 2009 xterra but havent been here in years.. lol.
