Mine was about that price too, but they also performed an alignment after the install. Hourly rate is ~$90-100 for the shop I used.

Folks, are there any tips/tricks to keep the intake temp down in between autox runs? My local autocrosses typically have 40-70 racers that are broken into (2) groups. It doesn't take that long for 35 racers to finish a 40 second course with (2) cars out at a time. I found my intake temp getting above 130F this past weekend based on a reading from my AccessPort. Early in the run it felt like timing was being pulled and power was slightly down. My last run (of 6) was still my hero lap, so maybe the lack of power doesn't affect me that much? Lastly, I don't remember what the threshold was for pulling power back from a temperature standpoint. Was it 115F?
I've tried several things to keep my intake temp down between runs.
- Hood up
- Leave engine running
- A/C on then turn off just before the run
I have not tried wetting my intercooler with a sprayer since my tires haven't needed a sprayer either.
My local club doesn't have an issue with me driving in the empty parking lot next to our venue. Maybe just before my run I should drive around the parking lot to keep air flowing through instead of heat soaking in grid? I've done it in the past to warm my tires up.

I sprayed the intercooler between runs
I sprayed the intercooler and even lightly around the engine bay
small garden sprayer with water to spray to IC down then some air movement helps to bring down temps. even a light spray under the hood on the intake pipe can help a little
I've thought about bringing my electric leaf blower...
