My car seems to run better at night, with my stock air intake, than in the day time. im guessing cause of colder air.
if i get the rai in 100 degree weather will it be as effective as cai in 100 degree weather.
i was looking to get a rai over the cai, unless the weather (heat) issue is a big problem. thanks

 

rai? do you mean sri? Short ram intake?

The colder one will do just that, get colder air. The difference is negligible in a stock application and both give a nice sound. I also live 100+ degree weather. You won't notice a performance difference with either in stock application but the ram will give the sound for the cheaper.

 

yes i meant that, rai = ram air intake but i know its wrong now!!
ok sri is good then, hmm why make 2 diff type if... they do the same.

 

They both will help throughout the entire powerband, but the CAI will give you more gains in the upper RPMs, whereas SRI will help more with low end torque and throttle response, which IMO is more important.

Plus, CAI's are more expensive, more work to install, and have much more chance of sucking up water and hydrolocking the engine. I live in FL, and if it rains in Texas like it does here, you definitely want to stay away from CAI because the filter will constantly be getting wet. If only part of the filter is wet it won't cause hydrolock, but you won't be sucking in air through the wet part of the filter and it will be therefore more restrictive and hurt your power when it gets wet. The SRI will rarely ever get wet at all and it won't get as dirty.

 

If the ambient temperature is 100, then your engine bay temperature may be 160 or more. Would you want your engine ingesting 100 degree air or 160 degree air? That's the difference between an SRI and a true CAI. We're talking 5 HP or more so keep that in mind when you buy.
