I have good fitting catches on my car. However, I am looking to fit rear extenders to help vent the underbonnet hot air. John Taylor was unable to supply as he was sorting something out with them so looking again. Anyone had any issues with extenders?
I installed the John Taylor extenders before the summer. Can't say I've been able to notice a difference in temps on my dodgy temperature gauge i.e. it still gets hot in traffic but Techniques told me they do help. And there have been no issues with the security of the cowlings.
