i want to begin to mod my TSX... i was wondering what are some good websites to order from or a shop in southern california to go to

 

everyone is gunna tell you to search but.....

looks like you got an intake so your on your way.
tsxparts.com
the official vendors on this forum are very good
and as far as shops in so cal i have no idea about since im from nj

 

where in so-cal?!!?

I know someone in alhambra selling stuff.

 

I don't think you'll have trouble finding shops to order from or help you install in So. Cal. There are so many shops i know i can order from but too bad i'm not local.
It would help if you tell us which area you live in.

 

so cali is the center of the automotive enthusiast industry...you'll find alot here.

www.heeltoeauto.com and www.tsxparts.com are vendors here (or i think the 2nd one is a vendor on the other TSX site)

As for shops, it depends on where you live...shops around me tend to die out within a year though =P
