Tony Kanaan and EJ Viso have both been given 10-place grid penalties for this weekend's IndyCar Series race at Iowa after their KV Racing Technology squad opted to change the Chevrolet engines in both drivers' cars.
Brazilian driver Kanaan, 37, took his best finish of the year last weekend at Milwaukee with second place behind Ryan Hunter-Reay. Viso's fifth spot was also his best of 2012.
IndyCar also confirmed that no post-race penalties were issued to drivers or teams following the Milwaukee race.
