I bought some silicone plug leads from the US. It has a warning "not for road use", why? Is this a US thing?

I recently bought a new set of Bosch (German) leads specific for a Kombi (type 4 motor) and they were silicon leads.
Haven't tried them yet but have been assured they are fine??

Warning would most probably be related to the shielding/interferance caused by the leads.If using "on road" they might cuse froblems with radios etc. Don't worry about it!!!!!:bounce

Could also be due to Cali "dont mod" laws.
They also have "off road use only" on K&N filters

In Cali i dont think you can even change underpants unless it is C.A.R.B. labelled

A month ago I went down to my local VW parts shop and asked for a set of silicon spark plugs leads. It was met with looks of horror and a warning not to ever use them. I think that the reason was the reliability of these new lead as the original leads are more reliable with the VW ignition system.

I bought the original type.

on the other hand i've ben using top gun silicon leads for six months with no probs from them per se.... but they have a different connection on the spark plug end and can blow off at high revs. meh. i just sqwished the bastards back on real hard... so far so good...:o

I have a roll of top gun stuff here that I cut up for people who wanna use it. It has a copper wire centre.I still prefer to use the original leads.:bounce

Hi

Im very impressed with Magnacore leads, very well made. When buying leads for an aircooled car you must ensure that ends near the spark plug fit the tinware properly. I have found silicon leads to be very fragile if they are removed often.

That's right. All to do with emission laws
