so i just got a little sri today, nothing fancy, ill post pics later, but i was wondering. is this a bad idea for any long trips to high altitudes? i live in san diego and im going to big bear for a snowboarding vacation with my dad for a week. its supposed to snow alot and im wondering if the altitude, thin air, snow and cold weather is gonna be a bad thing for the sri. i havent had any CEL's since i put it in so i guess thats good. any help is appreciated. thanks everyone.

Re: SRI problems in snow and high altitudes?

Should be fine in the cold, thin air (obvioulsy all cars perform less efficiently in thin air environments but the SRI should have no impact).

The main concern with SRI's is heat soak. So this summer if you hit the desert you may have issues but otherwise be fine.

Re: SRI problems in snow and high altitudes?

A CAI could experiance problems in snow depending on it's location, but an SRI really shouldn't have any problem. The altitude won't matter.

Re: SRI problems in snow and high altitudes?

so i think ill leave it in then. what's a heat soak? is it cauz the sri is still close to the engine? also i just got a cel im wondering if its because i just put the new intake on the car, when should it go away because it came on about 11 miles after i installed the sri. its about the same setup as this: http://www.mazda3forums.com/index.php?topic=135108.0
but i put a filter on the end of the breather hose. and here are some pics of the setup i have

Hot air contains less oxygen so when you're pulling in a lot of hot air you will experince a decrease in performance. This is heat soak. Some SRI's such as the Simota have a carbon shield to try and keep the hot air away from the intake.

The CEL won't go away if it detects a problem. If it came on after the intake install, then it is possible the intake is causing it. Get the CEL checked to see what the problem is or try putting the stock intake back and see if the CEL goes away.

I moved from FL to UT (long story) and I've had no problems with my SRI be it in the snow, dust, slush, rain. Well, I take the rain part back---it simply doesn't rain here :(

The whole heat soak thing with short rams is a joke and anyone with a scangauge or dashhawk can attest to that. The only time I'd say it would hurt performance at all is at the drag strip if you've had your hood closed between runs to keep all the heat in, but a CAI would suffer under similar conditions. Any of the SRI's "problems" with heat go away very quickly once the car moves. My intake temps are never more than 5º above ambient (be it 50º or 95º) shortly after moving and then sometimes they're the same temp:


Car felt great that night! haha

From my experience, I disagree with you on heat soak. Perhaps the 6 performs differently then the 3, I don't know.

Even in Seattle, during hotter summer days, in stop and go traffic, the engine would bog down. This was not experienced before or after the I had the SRI.

I had it bog sometimes with the CAI but never with the SRI.

I did the airbox mod and ran at the dragstrip back in Orlando a half dozen times, put the CAI on and it couldn't even match the gutted airbox after 7 tries. Put the SRI in and went back, immediately gained a quarter second.

No chance for hydrolock unless I drove into a lake pretty much sealed the deal. Strange, huh?

No it is not normal. Read my reply.
