WHICH IS BETTER?

WHICH IS BETTER?

Postby 98-ASTRO-SS [OP] » July 28th 2009, 11:15am

I want to put a air intake on my 98 Astro but want to make one myself. So my question is which is better a whole lot of hot air for your intake to breath or just get as much as I can muster up of cold air? I was thinking of running a cone filter either on top of where the factory box is or maybe trying to run it over in front of the battery if it will fit.If none of those spots will work I was wanting to run some piping out of my factory box on each end to try & find as much cool air as possible. I am new to these vans just picked up my first one last week. Thanks for your input

With any vehicle, cold air is better. Hot air (even warm air) will rob you of power.

Yep, the colder the better.

As far as I'm concerned, and this is just my opinion, the factory intake gives you much cooler air than any CAI kit on the market for these vans.

X3 the colder the better. The factory setup is about as good as it gets with these Vans, unless you put a hole in the hood! :twisted:

Thanks guys, I will probably just run another tube out the other side of the factory box to in front of the battery so the air would be cooler over there away from the motor. I was going to put a 50 series flowmaster on the van & was going to just remove the cat & replace it with exhaust pipe. Will this work or will I get a dummy light with this mod? Thanks again

anytime you remove the cat you will get a dummy light especially on 96+ models.

Which is highly illegal in the US. The EPA went after Jasper a while ago for selling oxygen sensor simulators. O2 simulators trick the computer into thinking what ever you set them too and are a big no-no when it comes to emissions. Jasper lost over $5 million dollars in fines plus was ordered to buy back any/all of the units they sold.

So no, no mention of "dummy sensors" here. :whistle:

You may or may not get a light....... I still haven't got around to replacing the cat on my '99, which is totally hollow, and in it being like that for 5 years, i've popped a catalyst efficiency below threshold code ( it's been so long i don't remember the exact code or wording of the description} maybe twice. I'd still recommend just getting a Magnaflow or Flowmonster OBD II certified high flow cat for it. ( I had one that ended up going on my '95). I've used the Flowmonster's on several OBD II vehicles with excellent results, and you can get them a lot cheaper than a Magnaflow. sorry for bad typing, i'm without use of the right index finger for a while, lol..
