Genr 5 Backfire

[pedro7680]

my gen 5 seems to be backfiring since getting a big power flow back box.

i know that the spark plugs are at least 4 years old, so they will shortly be getting replaced./

but anyone reckon i have anything to worry about here,

other problem is blitz state the induction kit ive got sounds the same as a class a rally car.. . . . with the back box, i must admit,, it does now really sound like a rally car and sounds like power!. the backfire doesnt sound too harsh, it does sound like the cars you see rallying!

opinions?. ( the plugs im looking at are 14 quid each from fensport, so im holding off as long as possible cos its a road tax month )

hey Pedro.

I`m in the same boat. Toying with replacing the platinum ones with Iridium. Also i`m running a Blitz air filter with a Scorpion S/S exhaust. And i do get backfires usually just as i change gear. No flames tho which is good :D

I`m renewing all the ignition components and fuel filter when i can find the b***** thing. Just got it back from having the cambelt renewed so all the timing should be ok.

Dont think it`s anything too worrying. Nothing seems to have fallen off yet.

a little backfire is nothing to worry about as long as it just that little....

i used to get it on the 2 when warm, little extra fuel going through the engine...

cheers lads,

my minds put to rest..

seems it is when the cars warm, and its sounding pretty mean,

3rd gear at 2000 rpm when i take the foot of the gas, a few seconds later it bangs,

then even 4th gear again 2000rpm foot off the gas and it does it,

i was just driving easily along the motorway today when i discovered this,

does it help with any potential info that i might be requiring?

thanks
