well what is the differece as no offence but alot of the car stuff is fashion based too

people swear by products, a few welknown cars get another part adn do some times then rae about it and then everyone follows like sheep

autronic being a good example, people saying get autronic onnthere car as mad rod has it, sunny took his pectel of his car for it

but if it makes all the difference for the power,,,,,,, im not sure


grs was the fasion a while ago, even thought the water temps where hgh people still fitted it and justified it

people followed and then pro alloy comes about and then people follow

radtec do a very good job for alot of people and never heard a prob with one

i got a pace and there shtie BUT its a fooking old design
