SCITOO Knock Sensor SU10549 Ignition Detonation Sensor Fit for 2006 for Acura CSX 2006-2011 for Honda for Civic 2006-2009 for Honda S2000

Works on 2010 civic si. Exact replacement part. I don't really trust it's coating so I added lubrication to the threads for the future replacement if necessary. I could replace this part 10 times before the oem price becomes cheaper. Im not sure if I would use this on a track car since It may be innacurate at detecting actual knock which can either cause damage or loose out on ignition timing but won't be a problem for normal driving. If you have large hands your screwed when it comes to installing it.

Update: almost a year in, still working. No problems!!! 8-20-21Bought this for my 09 Honda Civic Si. We accidentally broke it when I was having starter issues, (hitting the starter to get it to crank until I replaced it. It be like that sometimes...) anyways, compared to paying $80+ at the parts store, I decided to go with this one as opposed to the others because of the one written review. All others were just star ratings. So ty first person! I’m only 1 week in, if I have any issues I will update. Other than that can’t complain!!!
