maybe this "mod" is a given not worth mentioning, but you can lighten your car by about 100 pounds by stripping out the spare tire, jack, tools, owners manual, etc. this does make a noticeable difference

I recommend removing the one closest to the manifold.... Cats retains lots of heat.... your Yaris manifold "heatshield" isn't really that effective... especially after a drive and you come to a halt. I always have a problem with Engine bay Heat management..... |

I talked to some TRD represatives about the issue of what exactly is the celica hoodscoop used for ? I was told it's mostly for drag/downforce issues and some engine airflow characteristics. Helping with higher speed stability of the FWD. And air circulation around the motor for cooler under hood temps. They said blocking off the scoop or hindering the airflow lessens the airflow through the engine bay and decreases areodynamics. |
