I've been talking to some friends and they all have rave reviews about the efficiency of a cold air intake. I've been wanting one for a while but i'm not sure which way to go. some of them made a custom system, others bought theirs online. I just want to know which one is best for '98 Volvos

Do you already have a high flow air filter like K&N or Green Filter? Cold air intake is debatable. The air is coming in so fast it really doesn't have time to get that hot. I would like to see a dyno of a before and after mod on that.

everything's stock. I have a purolator filter with a stock airbox, hoses, and a rebuilt air meter

Is the air meter factory spec? I would think you would get more 'bang for the buck' with a high flow air filter before a cold air intake. Ultimately you would benefit from both, but I am not I big believer in a cold air intake for your car is going to make a noticable difference.

ghost twin, I have a 05 V70, na, and installed a Scepter induction system replacing my existing air box and K&N filter. After 2500 miles at ambient temperatures from 70 to 10 degrees F, I can say that: average MPG increased by 1 ($2.79 for each saved gallon) the wide variation in temperatures does not seem to have any effect, noise level (as long as you don't have a lead foot) is only slightly more noticeable. I am still in the learning processes in how to drive the "new" intake system, I have had up to 30 MPG on back roads and 32 on the highway (I still need to take a road trip on the highway for more than 1 or 2 hours to really find out where it is at). Sometime in the near future I will be building an air box to see if a little extra air pressure makes any difference. The Scepter system is perfect for those of us who like to tinker it is made in 4"-6" sections (straight, 90, 45, 60, and 22 degree bends with both 3" and 4" IDs available) so that you can customize your system the way you want it. It took me about 3 hours start to finish to remove the old and install the new to the way I wanted it. The 3" sections are made from some type of chromed hard plastic with "O" ring seals and clamps for each section, one of the adapters allows you to keep your original air flow meter and another allows you to hook up to 3 vacuum lines so that you don't loose your emissions controls. They also make a kit that you fit-up the way you want you send it back to them and they makeup an all metal (welded) induction pipe if you want. Good luck, davidmmcssssw.
