A.R.E are good cooler thats a given but i bought the hybrid super monster cooler (600x300x76) off flyn perfornamce direct very very good to deal with indeed answered any questions i had sytraight away...... the cooler on my car is supporting boost up to about 1.5 bar (22psi roughly) and had helped me make 275 rwhp with a shitty standard ecu with air fuels all over the place easilly be tuned to over 300rwhp at like 16 psi...... overall i reccomend these coolers and also reccomend flying performance aswell....
