Benifits noticed, my gf car is stock, has 20K LX 7th gen civic.
1. Stronger Starts.
2. Smoother Automatic tranny, it some how responds a little quicker.
3. Brighter Head lights, stock head light blubs. Brigther than my neighbors PIAA's on the same car. LOL..
4. Throttle Response is improved. First thing i noticed when i drove the car.
5. MPG should be improved havent watched the odo to really keep track. She goes to calpoly and did notice a little better mpg.
6. Buzzing from a bad head unit ground is gone, she has a pioneer head unit about 1 year old sounds a little clearer, just the highs.
The grounding points arent the best but feel free to explore and look for better grounding, as i would have had better acess to more points if my gf had an intake or something. I will be doing a install on vanillaman's car.. soon. so look for his review.
