**Cold Air Intake Test: Acura Integra GS Performance Analysis**
In this video, we delve into a comprehensive performance analysis of a cold air intake installed on a 1999 Acura Integra GS. The test compares the cold air intake with the previously tested short ram air intake, focusing on acceleration times across various RPM ranges under controlled temperature and humidity conditions.
**Introduction to the Test**
The video begins by inviting viewers who haven't watched the earlier short ram air intake test to check it out first, as that serves as the baseline for comparison. The cold air intake was installed after removing the short ram air intake, and testing was conducted again under identical environmental conditions—temperature at 56°F and humidity at 72%.
**Testing Setup**
The testing methodology involves measuring acceleration times in different gears and RPM ranges. Specifically, the test focuses on:
1. **Second Gear Run**: Acceleration from 20 to 40 mph.
2. **Third Gear Run**: Acceleration from 20 to 40 mph (lower RPM range).
3. **RPM Range Analysis**: Acceleration times broken down into low, mid, and high RPM ranges (2000-6000 rpm).
**Results Across Different Gears**
- **Second Gear Performance**: The cold air intake achieved an average time of 2.84 seconds, which is 0.97% faster than the stock intake in the mid to high RPM range.
- **Third Gear Performance**: In the lower RPM range (third gear), the cold air intake was notably slower at 4.61 seconds, a 3.95% decrease compared to the stock system.
**Detailed RPM Range Analysis**
The test further breaks down performance into three distinct RPM ranges:
1. **Low RPM (2000-3000 rpm)**: The cold air intake was marginally slower at 1.36 seconds versus 1.33 seconds for the stock, a 2.27% decrease.
2. **Mid RPM (3000-4000 rpm)**: Here, the cold air intake showed an improvement of 1.3%, indicating better performance in this range.
3. **High RPM (4000-6000 rpm)**: The cold air intake excelled significantly with a 4.64% increase at 4000-5000 rpm and a 3.08% improvement at 5000-6000 rpm.
**Conclusion and Recommendations**
The test concludes that the cold air intake offers substantial benefits in high RPM scenarios, making it ideal for track or drag cars where higher revs are common. However, for daily drivers rarely exceeding 3000 rpm, the cold air intake may not provide noticeable advantages and could even hinder performance.
**Final Thoughts**
The video encourages viewers to leave comments and questions below, emphasizing the importance of understanding one's driving habits before investing in high-performance modifications like a cold air intake. The results highlight the need for drivers to consider their usage when making such upgrades.
"WEBVTTKind: captionsLanguage: enhello everyone and welcome in this video i'm going to be testing out a cold air intake on my 1999 acura integra gs now if you haven't yet watched my video on the short ram air intake testing you may want to check that out first as that's where i'm going to be pulling the test data from for the stock run i actually used the same stock run that i installed the short ram air intake took that out installed the cold air intake and then ran the testing again so what we're going to be looking at different rpm ranges to test out uh now the temperature and humidity for this run i managed to get the temperature the exact same i waited for the right time of day to test the humidity was off of it so 56 for the stock run uh 72 percent for the cold air intake so let's get started with the second gear run from 20 miles an hour to 40 miles an hour so for the cold air intake a time of 2.84 seconds that's the average so 0.97 percent faster about 1 faster than the stock air intake in the mid to high rpm range when going from 20 to 40 in second gear so let's check out third gear 20 to 40. so an average time for the cold air intake in the 20 to 40 mile per hour range for third gear this is the lower rpm range of 4.61 this is almost four percent slower than the stock air intake system so significantly worse so things aren't looking good for the cold air intake but we're going to take a look at the low mid and high rpm rev ranges i did an acceleration test in second gear from 2000 rpm to 6000 rpm and then broke out the individual times for each rpm range so we can see you know how is it affecting each individual rpm range so let's get go ahead and check out that video so very cool results when you break it down by rpm range so 1.33 for stock in the low rpm range versus 1.36 for the cold air intake and this gives you a negative 2.27 percent difference so the cold air intake 2.3 percent slower in the 2000 to 3000 rpm rev range now one thing i want to note just so if you you know want to back calculate some of these numbers these here are rounded to the nearest hundred but when i calculate the percent difference i use the full number that i had for each one of these so it may look a little bit different but it is calculated using the full number that i have which is based on 120 frames per second and taking the number of frames so anyways looking to the mid rpm range uh we're looking at a percent difference of 1.3 percent so the cold air intake in the 3000 4000 rpm rpm rev range is actually 1.3 faster for the high rpm rev range this is where this cold air intake is really starting to shine uh 4.64 faster in the 4 000 to 5000 rpm rev range so pretty impressive there and 3.08 percent faster in the 5k to 6k rev range so significant improvement on the high end uh worse on the low end in fact much worse in the very low end this is you know 1500 to around 3000 or so rpm so four percent slower there but what you can see is that there actually is a significant improvement for the high rpm rev range so what are our conclusions when should you use a cold air intake well if it's for your car that's specifically a drag car or a track car it makes a lot of sense because you're going to be keeping it in the higher rpm rev range and you're going to get that acceleration benefit now that said if it's your daily driver where you're going to be staying in the lower rpm rev range you're going to be losing power so it doesn't make much sense to do when i was using my integra as a daily driver i'd rarely get above 3000 rpm and as you can see 3 000 rpm the cutoff below it everything is slower so for a daily driver it doesn't make a whole lot of sense if it's purely a track car where you want to take advantage of that high rpm rev range and that's where you're going to be staying then it does make a lot of sense so any questions or comments feel free to leave them below thanks for watchinghello everyone and welcome in this video i'm
