I'm about to book a whole set of preventative mods on my 335d and including part of that will be swirl flap blanks. I've been told by every company it's the larger ones for us 35D boys so 32mm. I'm going with PWM ones but anything that comes with O rings should do the job. I'm going for PWM just because MOB17 who has had his car tuned to 422bhp and running the highest BHP/Torque for a 35D in the UK got his blanking plates from PWM.
There's not a lot of diff between them and say ones from ebay.. just down to budget really. PWM for a set of 6 I think costs about £35 whereas Ebay ones cost about £20 IIRC?! HTH |
