I blew my airbox after 25 years coz the Bentley was misprinted and I put the wires on the wrong way , blew the damn thing to smithereens with screws and plastic everywhere , no pop off in the world would have saved it.
Put the new one in with no pop off and don't regret it for a second ( 12 years ago or so ) . car never backfires even when it struggles to start on occasion and the idle drops right off. New airbox had plenum in it though.
I truly believe if it backfires something else is wrong, others I am sure disagree. I am in Canada and swing for 32C in the summer to -15C in the winter and still it never backfires so im not going to do surgery on a healthy patient.

just my 2c.
