Thinking of fitting one to my Sti5, is it gonna have any destructive effect on my MAF sensor or is this one of the "safer" mods ?
Was also thinking of fittin a Turbo XS VTA dump valve, getting put off by conflicting reports of screwing up the fueling on lift off.

Any comments ? are these mods going to increase the probability of another V5 engine failure.....which i aint wantin !!!

The car at the moment has a scoobysport backbox and magnex decat centre pipe.

Best regards,
Kevin.

 

I have one on my P1 and its fine / the blitz LM filter dont let as many molecules through as much as the hks powerflow/aps which means the maf should be ok.
Make sure you fit the support bracket and becarefull you dont knock the maf sencor about when fitting.
