Cold Air Intakes

I have the Vi intake. Pretty sure he's out of business bu love th intake. And with only an intake tune is not necessary.

check with @gpcustoms, he's got a nice CF look coming out. Plus it helps with the cancer foundation. There are a few choices out there. Look around and make it your own. Welcome, great crew here to help you out

What @Shatneyman said! I bought mine used and a full blown intake was already on it. Looks okay, not sure what stock felt like, but the fit seems unfinished.

I like the @Turbosling Alpha look and colors. . .

I installed the Injen about 1000 miles ago. $237 with shipping is what sold it for me. I'm very happy with it.

I have the Alpha CAI. I chose it for 2 reasons. First, they have multiple colors available and if you are looking to accent your engine compartment, that is a big help. There is no added charge for the extra colors. The second reason is that I like the aluminum piece that is placed in between the manifold and the throttle body. It makes a nice clean, unrestricted transition into the engine. I don't know if it is overkill or not, but it looks cool.

As far as a tune, do you need one, no. Do you want one, hell yes. The change in drive-ability is huge. The throttle response is much improved. If you plan on an exhaust, I would get that as well before you get the tune so you will only have to do it once. In my opinion, it was some of the best money I spent on my sling. It is so much more fun to drive, especially if you are a "spirited" driver. I sent my to Bob on a Saturday, and had it back by Wednesday, so you won't be down long. You won't be disappointed.

You could always come to the SSITS17, Bob was there last year doing the tune's

alpha for the win.

I had mine installed and Blues & Booze by Slingshot only, so far I love it.

I bought a Hahn CAI during last year's Slingshotonly Black friday Sale. Engine seems to run like it did before up until about 3500 rpm, at which point the CAI's kick can definitely be felt as there is a distinct difference once you hit 3500 rpm!
I picked the Hahn over the Alpha because I liked that the Hahn sealed against the bottom of the hood and I didn't want to hassle with re-positioning the TBI. I had originally planned on going the DIY CAI route using the Cobra-headed adapter to provide a smooth-flowing transition fromt he CAI tubing to the TBI, but the Hahn CAI's sealing against the hood mad me decide in favor of the Hahn.

I installed the injen Cai. It looks good and serves the purpose but it is not as pretty as the alpha. I never open my hood to show anybody anything except when to change the oil. So if you're into looks get the alpha if you're into performance and price matters ingen is the same. Buy from the injen site. Slingmods is $100 more.

Aren't those Eastwood lights awesome?! Love mine...

For those "in the dark" on what I'm talking about, I'm referring to the LED light bar Chad is using across his hood in his pics. Here's my thread on The Dark Side about these awesome lights (even back then, was trying to bring Slingers to The Light... ). BTW, I have no affiliation with this company, just really like the product:

My 2nd post here

This is my current Cold Air Intake and I am quite happy with:

Not sure if it is still available, but often people who upgrade to a Turbo will post their used CAI here on the forums.

ALPHA intake/exhaust

Could be a real deal sitting right here for the taking

If Hahn ever ships my turbo kit, I'll have a Hahn CAI for sale.

Update - Just heard from Hahn and my turbo should be shipping the end of this week! With any luck, I should have a Hahn CAI for sale in a few weeks.

The only time a tune, or an ECU modification is required, is when the engine uses a MAF (Mass Air Flow) sensor to control the air/fuel mixture. These engines don't use MAFs, thankfully.

While it is true that any mod(s) short of a turbo/supercharger doesn't REQUIRE an ECU reflash, I don't recall anyone who has gotten an ECU reflash after adding a CAI and/or a muffler/exhaust system who has stated they wished they had NOT gotten the ECU reflash. Typical reports are smoother engine performance and more output than obtained just from the CAI/Exhaust/Muffler changes.
The ECu reflash is included in turbo/supercharger systems and for a normally aspirated engine costs an extra $500 ($400) if the Group Buy on the other site is still in effect. The thread hasn't been updated for several months. See - ACTIVE Group Buy - ECM Tune from Mefi Bob for NA Slingshots | Polaris Slingshot Forum as there are comments from folks who have gotten the reflash w/o going turbo/super.
