Speaking for myself, i didnt buy a 4runner to race stoplight to stoplight. bought it to go offroad, sand, small rock crawling. the 4runner definitely has issue on the low end. the SC would help fix that. extra power on the pavement doesnt hurt neither but yes...ALOT OF MONEY.
thinking about buying right now
looking at the Mag SC. best deal is $5.4K w/o installation. been going back and forth on it. not much on videos on the web about it.
Yours says red. Ebay has another one with yellow in japanese.
