bandit_287 Posted July 24, 2021 Report Share Posted July 24, 2021 Can anybody recommend some decent wiper blades, I’ve used Bosch Aerotwin for years but recently the quality is not a patch on what they used to be, they used to be very quiet and last for at least a year but now I’m finding they need replacing after a few months as they become noisy. I’ve heard good things about PIAA silicone blades? Quote Link to comment Share on other sites More sharing options...
Paul P Posted July 24, 2021 Report Share Posted July 24, 2021 Used both Bosch and OEM. Very similar results. Worked well. Had both for 18 months. Different cars. Both lasted that time. heard good things about the Pisa as well. for 30 quid ish a set I am ok with changing them every 6 months if it come to it but recently I have found a clean of bith wiper and screen seems to bring them back to life.

michelin Posted July 25, 2021 Report Share Posted July 25, 2021 PIAA. Not the cheapest but they are the best I’ve ever used. I found them cheapest on ebay. 👌 Quote Link to comment Share on other sites More sharing options...
bandit_287 Posted July 25, 2021 Author Report Share Posted July 25, 2021 I think I’ll try the PIAA, I’ve heard very positive reviews about them, they’re not cheap but worth a punt as noisy wiper blades are very annoying. The quality of Bosch blades have really deteriorated over the past few years in my opinion, I’ve used them for probably 20 plus years and they were excellent and lasted ages but as of late I’ve found they only last a few months before losing their efficiency.

Richard Hamilton Posted July 25, 2021 Report Share Posted July 25, 2021 I've used PIAA wipers on all my cars for the last 15 years or so. Wouldn't use anything else. 1 Quote Link to comment Share on other sites More sharing options...
graham964 Posted July 25, 2021 Report Share Posted July 25, 2021 I would like to get a set of these for my 981. Is there a part number/size Thanks Graham Quote Link to comment Share on other sites More sharing options...

GladysFriday Posted July 27, 2021 Report Share Posted July 27, 2021 I put some Heyner blades on my wife's car and they seem to be good. German-made and considerably cheaper. Another option perhaps? https://heynershop.co.uk/index.php?controller=partsfilter&type=4&make=29&model=311&body=570&year=1811 Quote Link to comment Share on other sites More sharing options...
smartin Posted July 28, 2021 Report Share Posted July 28, 2021 Wish I'd seen this a couple of weeks ago as just replaced the wipers with Bosch Aerotwin. Not been out in the rain, yet, so no idea what they are like. Think they replaced Porsche blades as couldn't see any branding on the old ones but there is a very clear Bosch logo on the new ones. Hadn't touched the old blades in the 2.5 years I've had the car but with the OPC commenting that they were a bit smeary at the last service back in November and the MOT coming up, thought I should replace. Only £20 from Amazon so not a biggie if they end up being no good Quote Link to comment Share on other sites More sharing options...

For 981 Boxster S, it said "not compatible". Checking the PIAA web site seems to give the same result - the only Boxsters in the model dropdown are 986 and 987.

bandit_287 Posted July 28, 2021 Author Report Share Posted July 28, 2021 (edited) You only need a 21/22inch, 530/550mm blades. PIAA confirmed the sizes for me directly. They should come with the relevant connectors, IL4a is the connector our cars use. Edited July 28, 2021 by bandit_287 Quote Link to comment Share on other sites More sharing options...
graham964 Posted July 28, 2021 Report Share Posted July 28, 2021 Thanks for the feedback. My car is under warranty, would fitting the Piaa or Heyner blades invalidate it? I assume OEM was Bosch Quote Link to comment Share on other sites More sharing options...
MH82 Posted July 28, 2021 Report Share Posted July 28, 2021 They can be pretty arsey but it depends on the dealer. Given I’ve claimed over £20k in warranty work so far I was ‘happy’ to go with Porsche blades rather than p*ss them off with Bosch….. (for the sake of £40) Quote Link to comment Share on other sites More sharing options...
bandit_287 Posted July 29, 2021 Author Report Share Posted July 29, 2021 You can always swap them over to the OEM wipers if you need to take it in for inspection or service etc. It takes a few seconds to do. Quote Link to comment Share on other sites More sharing options...
