Backfire screens are manufactured into filter cages to prevent the hot sparks generated by a backfire from igniting the foam air filter.

However, the desire for better airflow – and the resulting increase in horsepower – has led to risky modifications. For years, racers have been nervously cutting out the backfire screens from their stock filter cages.

Those days are over. The new weapon of choice is the No-Toil Super-Flo Filter Kit. A revolutionary solution, this complete system safely replaces your OEM filter and cage assembly. Thanks to a flame-resistant treatment on the filter, you can backfire and spark all you want – the filter will not hold a flame.
