    Struggling with justifying the cost of the EPP air intake after already owning an Airaid. If I was on the stock intake I'd jump on the EPP because it looks like roughly a 7-8 HP gain over 5,000 RPM versus stock.

    Does anyone know what the difference is in HP comparing EPP to Airaid?

    The EPP not only increases horsepower by 5-7 it also frees up the wastegate duty cycle on the turbos allowing them to work more efficiently. Something like 7% lower WGDC over a box replacement intake.

    Do you have any sense what that might translate to in real world performance e.g. ET or 0-60?

    I don't have any real world data. @mattr66 dynod the j2 which eventually became the epp intake. His findings were something like that. Basically you'll be able to maintain higher boost on stock turbos longer before it tapers. Especially with a hpfp upgrade it'll be worth while because I'm assuming your running more than 15psi or trying I should say with these baby turbos

    Looks like I'll have to get the EPP then. I have the HPFP and hoping to upgrade to Matt's turbos shortly.

    I literally just purchased my EPP intake this morning. The 7hp gain was compared to the Airaid intake from everything I researched. And it was an 8% drop in WGDC which is HUGE for us pushing these cars to the limits on corn. Plus, the look is lovely!

    Ok I broke down and ordered it. This car is truly an addiction.

    Looks sharp. Like that flat/matte black finish.

    Looks well made. The pipes sure need to be heavily cleaned out with some tool.

    Looks like it may be a textured wrinkle finish. hard to tell.

    No instructions with it so hope the install goes well. Thinking also about how to scrub the stuff out of the pipes.

    mine were clean, luckily didn't have an issue. Brake/carb cleaner will loosen it up then just run a rag through it.

    As for instructions, this was a thorough review and install tip from a Facebook customer:

    -----

    Review and install instructions of our cold air intake by Grant Rose:

    Alrighty so here’s my review over the Eco Power Parts/ J2 fab/ Hennessey Performance “twIntake”

    Mike @ EPP makes a very well put together kit. After talking with guys that had the J2 intake they said mikes kit fixed a lot of issues the J2 kit had so if you are in the market to buy one used, go with the EPP one over the J2.

    I chose raw finish to keep cost down, I wanna say with taxes shipped it came out to $467 or $487? It retails for $450 I’d have to double check on what it came out to with taxes but it was for sure well under $500. The J2 when new was $600 I think?

    My over all first impression of this intake was the welds are very clean, I had debated wrapping it with gold heat tape of painting it wrinkle black but ended up leaving it raw. Install was not bad, I had the stock intake piping out within 10 mins start to finish.

    You will need a 8mm socket, a 10mm
    Socket and a 12mm socket for the removal and install of both stock and EPP intake and a flathead screw driver potentially just in case one of the 8mm bolts is hard to reach with the socket.

    I suggest pushing the air filter into the heat shield and letting it sit somewhere warm for a day to help make ease of install a breeze. I let mine sit on my back porch for 2 days before installing to help break it in. You will see what I mean when you buy one LOL

    When it came to the install of the EPP intake start to finish I had in done in just over a hour I took a few soda breaks and was on Facebook talking to a couple other SHO guys asking for pointers etc.

    I started off with the rear turbo pipe first, it’ll feel weird pushing it into the stock coupler because it doesn’t go far in but just hold it in place and tighten it down. I removed the rear turbo hot pipe to make ease of access easier lol it’s easy for me because I have the EPP hotpipe kit not sure how bad it would be with stock pipes ‍♂️

    After I had the rear pipe secure I began working on the front turbo pipe, for this one you are going to want to re-use the stock clamp off the OEM pipe, the t-bolt clamp supplied by EPP is a little hard to get to fit over the coupler when forcing it onto the turbo. So re-use stock and just slip it onto the turbo then tighten the clamp down, then put the pipe in place and tighten that clamp down.

    Now make your way back up top and add the 2nd section for the rear turbo pipe aka (the middle and final piece)

    That one is a breeze not really any explanation needed honestly.

    Onto the heat shield, start from the piping and slide it downwards and toward the headlight and it will wiggle into place, remove the 8mm nut on the fender slide the heat shield into place and re install the nut.

    For the filter I found it was easiest to slide the filter into place then take the piping and push them through the heat shield into the filter completely past the point where you would clamp down (you’ll see what I mean the diameter changes) and then once it feels loose push the filter through the holes on the heat shield and then pull the piping back out until it’s snug and then use the clamps supplied with the filter and not the piping kit the tbolt clamps that come with the kit are too wide in my opinion.

    The rubber grommet that mike includes is for the IAT sensor. Just slide it over your IAT sensor and then push the IAT and grommet into the hole on the filter for it. It feels snug, I left it alone but I will buy a small clamp for it to make sure it won’t fall out.

    Now, if you’ve stayed with me this long into the good stuff- PERFORMANCE- only switching to the EPP from a air raid intake and not changing the tuning I noticed the car feels a lot more docile under regular driving conditions, it’s almost as if you really can feel the turbos are no longer fighting one another for air. Car drives a lot smoother honestly.

    Noticeable increase in turbo spooling noise over the air raid.

    I use a Dragy GPS device, I tried to get data in as similar conditions as possible (weather, D/A, altitude, temp) to compare the intakes, I noticed a average gain of 0.20 seconds in the 8th and 1/4 over the air raid intake by switching to the EPP and I also gained a average of 1.5mph over the air raid too.

    I highly recommend this intake to anyone on the fence about buying once!

    Also as far as IAT’s go, there are about the same maybe a tiny bit less compared to the air raid. I am seeing about 5* warmer over ambient while at highway speeds cruising and about 15* over ambient when making pulls over and over and over and finally about 50* over ambient when at a dead stop in traffic.

    Very helpful. Thank you Lee. I don't see any rubber grommet in the v2 gear.

    I bought mine for the increased spinny spinny whoosh whoosh noises. If it gets a little increase in performance that is just gravy in my book.

    I didn't see a rubber grommet in mine either.

    Correct, the entire filter was redesigned for ease of installation. The pipes are no longer blown out, and the IAT bung was reduced to match the size of our IAT.

    since you have the same mods as me you'll notice a drop in wgdc and some extra power. Stockish cars don't see near the gains, it's pretty similar to the Airaid in power but I'd still recommend it for anyone planning more mods in the future.

    Yeah. Cost is a bit much so I'm making my own. Been working on this for about a week now.
    Here's the template for the air box
