MartinT 514 Report post Posted May 24, 2019 I've ordered one of these HKS Intake Ducts, the shorter mark II, to replace the standard snorkel. Having done pretty much everything else to get NA performance, it seems silly not to replace the snorkel with something better. Has anyone tried one? Share this post Link to post Share on other sites
Badger 63 Report post Posted May 24, 2019 I have the earlier version. Sounds a bit louder on wot. Sent from my LYA-L29 using Tapatalk Share this post Link to post Share on other sites

Church 209 Report post Posted May 25, 2019 I guess more noise, as these replacement snorkels lack stock snorkel resonators, that would had removed some frequencies .. Share this post Link to post Share on other sites
MartinT 514 Report post Posted May 25, 2019 Looking at the standard snorkel, it does look restrictive. Ah well, it doesn't look too hard to replace so we'll see. Share this post Link to post Share on other sites

It's not, and Cosworth didn't find it a restriction on the SC either. Share this post Link to post Share on other sites
Deacon 1357 Report post Posted May 25, 2019 Interesting design change. Wonder if they're expecting it to be used with a bumper cutout? Share this post Link to post Share on other sites
MartinT 514 Report post Posted May 25, 2019 I believe they redesigned it because the previous big scoop version restricted airflow to the radiator? Share this post Link to post Share on other sites

Can't see there being much restriction to the radiator with the old version. From @Badger pictures above it doesn't seem much different to the oem set up in terms of any radiator coverage Share this post Link to post Share on other sites
MartinT 514 Report post Posted May 25, 2019 Agreed, but I read that on my search through the internet as to why the design changed. HKS only talk about "10x the opening" in their blurb. As for the Cosworth SC, surely forced induction gets around any restrictions in air flow, to a degree? It's NA that needs every assistance in getting more air into the cylinders.

No, you want the least amount of restriction upstream of a positive displacement blower. As said, the OEM design is to help remove noise and resonance. The sizing is perfectly adequate for 200bhp. https://www.ft86club.com/forums/showthread.php?t=49634 https://www.ft86club.com/forums/showthread.php?t=56341 Share this post Link to post Share on other sites
MartinT 514 Report post Posted May 25, 2019 So a little more throttle response and a tiny bit more torque. What's not to like? The FA20 needs every bit it can get. Share this post Link to post Share on other sites
MartinT 514 Report post Posted May 30, 2019 Got it done. Refitting the bumper is a bit of a bastard.No change in sound that I can detect (so much for all those resonators), but it's a bit more willing in pickup and revs nicely. Not a lot in it, so marginal value.Sent from my LG-Q6 using Tapatalk Share this post Link to post Share on other sites
MartinT 514 Report post Posted June 1, 2019 I did the HKS a slight disservice. Further driving reveals a noticeable willingness to rev to the red line - my rev limit light (set to 7000) flashed twice in the last day, catching me out while accelerating onto the motorway. From that point of view, it's worth having as overtaking is a touch easier. Still no change in sound from before, which doesn't bother me as the exhaust is loud enough anyway.

MartinT 514 Report post Posted July 21, 2019 I finally (today) removed the bumper and refitted it properly. Did I say it's an arse? You really have to guide each tab into its correct location and some just want to go the wrong way which causes gaps and much swearing. I still like the HKS intake, there doesn't appear to be any downside at all. It even sucks air at the same height as the stock intake so there is no greater risk of a water lock through deep water.

I was inspired by this thread and the results of the tests they had done: https://www.ft86club.com/forums/showthread.php?t=56341 I have not cut mine as far back as they have done it in that thread however, that was a bit too far for my taste. Simply said, it is a tight job to get it all done, but yet your hands in there and unbolt the snorkel and move it out towards the left hand side and you can pull it out. Cut the snorkel and you can slot it back in via the right hand side. Share this post Link to post Share on other sites
