Hi guys, im new. I have a 98 Aurora 4.0 and I was going to buy a cold air intake for it, but I heard the metal intake tube get reall hot and actually hurts performance. Is this true? If so does anyone make a cold air intake that doesnt have the problem, or can you do something to protect the tube from the heat? How about the RSM CAI?

the metal pipe does transfer heat more than the stock plastic, but if you wrap some heat-resistant insulation around the intake pipe you can protect it from heat. The stock airbox setup actually is very similar to a Cold air intake because it draws air directly from the fenderwell. The stock airbox flows pretty decent with a K&N filter and the gutted airbox combination. Hope this post was helpful.  |

Yup. As Custom said, the Aurora already has a stock "cold air" setup since the intake doesn't suck in air from the engine compartment. You'll proabably actually lose performance by buying an eBay intake kit, with a cheap cone filter exposed right next to the engine. It looks cooler I know...  Check out this thread: K&N + airbox gut for a fairly detailed discussion on intakes and modifying the stock airbox. Welcome to the Club!! |

i still decided to go the short ram intake way, that's exactly what it is, it doesn't allow for cold air unless you either build a box to shield it from the air inside the engine bay or keep the stock intake. i do notice an improved high end though, once the car gets up to speed it becomes very snappy and responsive (not that it isn't anyways, but a little more-so). i'm expecting this summer to make myself an airbox to help against that hot air.
i think the rsm intake isn't really even cold air (is it?), i think it's short ram intake.

does anyone make a plastic cold air unit? and is RSM shortram have the same problems with heat? and would a metal unit wrapped with insulation perform better than the airbox gut and K&N?

You'd have to try and let us know! I'm not sure anyone here has ever had both setups, in order to compare them. |

does anyone make a plastic cold air unit? No, not to my knowledge. And I've looked pretty hard. Yes. RSM's is just a higher priced K&N model. I doubt it. I think you would do better emulating Aurora40's set up with airbox gut, then wrapping the result with reflective material. No problem with going over this again as we do have lots of new members. But the Aurora already has a plastic cold air box that draws from under the fender. You can make it look like all the other plastic box cold air intakes by ripping out all the plastic baffles that help deaden sound. Whether this adds any power is up for debate. Dyno tests say no peak increase, some interpret the charts as having a broader power curve. I don't see much at all for the labor. However, no one to my knowledge has done "the gut" concurrent with throttle body and exhaust mods, and dyno'd before and after. So there's still a lot of room to bounce this topic around, it's why these bbs are so much fun. ;D |
