H3 Alpha Cold Air Intake (Non-Existent)
I recently upgraded to an Alpha, and I am perplexed that there is no options for Cold Air Intake. What's this all about? They have them for the 3.5, and 3.7, but nothing for the 5.3. Is the Airbox and intake on the Alpha so top notch nobody could do any better? I've seen the AirDoc, but that's just the tube, and it reuses the existing Box. What about something from another vehicle? Like a K&N for a Silverado with the 5.3 or something. I think the lack of options is kinda strange to be honest.

probably because there is not enough demand for one on the alpha.
|
As rep from the K&N R&D department said to me"it has a straight air tube how do you improve the air flow"
|
Special news flash...... even the OEM panel filter in that "existing box" outflows a K&N cone filter on the end of an open 3.5" pipe. Bump that to a high flow OEM replacement air filter. The weak link IS the OEM shape and resonator chambers.
Closed systems work. :cool: There are not enough GMT 355 and 345s (H3s) for the big boys to bother with. Volant gave up on them after initially offering an intake that suffered from fitment issues. There is also a significant challenge to making intakes for the Alpha that does not justify a scale investment such as with the cookie cutter trucks. |

Been running AirDoc Alpha system on every one since 08. Better mid range power and it gets rid of that nasty bottle neck 90 degree that the OEM has to smooth the throttle response all the way form idle to redline. Take your OEM off and a look at how it tapers to a 2.5" opening at the bend...:eek: |

X3. We wouldn't wheel with an open system. Then again we don't own street queens. We have AirDocs on our Alphas (H3 & H3T) with AFE Pro Dry Filters (none of that oil crap K&N junk that just fouls us your MAF). Remove, wash, dry, reinstall.

What is the part number for your AFE Pro Dry Filters
However, if over oiling is not a concern, there is nothing wrong with a K&N P# 33-2408. |

At my place of business... :rolleyes: we recommend the AFE Pro Dry-S for the 2008+ H3s P# 31-10171 Got one in my 09 Alpha Off Road with our intake. However, if over oiling is not a concern, there is nothing wrong with a K&N P# 33-2408. |
