the grill makes all the difference... ran just the grill for a few yrs... thats what really cools the car down.... the vent just let more underhood hot air out
Before I put the cossie grill and vents in My XR ran a little above 1/2 on the temp gauge.... Now it gets to 1/4 maybe a 1/3 unless I'm stopped in traffic... then it's still below a 1/2
I got mine off the back of a Ford Pick up.... Mine is the same colour and shape of the "Cossie" one..... And Yes I compared it to one on a Gennie Cossie here in vancouver
I installed some DTM Touring Car mirrors on My XR... Lots of fab work, but I think the results are worth it http://i62.photobucket.com/albums/h97/mrgixxer13/XR4Ti/IMG766_zpsa7e55332.jpg http://i62.photobucket.com/albums/h97/mrgixxer13/XR4Ti/IMG767_zps73e4240f.jpg http://i62.photobucket.com/albums/h9...
