LS1 Leads. Which are worth buying?

[Fu Manchu]

I’ve read that Granatelli are quite good to buy. Just that there’s none around at the moment.

10.5mm Eagle?
NGK? (7 or 8mm I think)
10mm Top Gun?
Aeroflow x-Pro?

Will use AC Delco plugs. New aluminium shields, and heat sleeves too.

ive got some aeroflow xpro in a kit to make up so cant comment on there usage yet but seem good quality, i did have some granatelli zero ohm leads and actually noticed a change in engine idle note from them (better spark maby) but i did get interference on go pro camera from them i would still be using them if i didnt move the coils, factory are fine also but if cost more then good aftermarket then just go aftermarket, dont worry too much about the size 8mm 10mm as that is just insulation the leads are prob all the same or as i see it poor bigger insulation just to say 10mm lead or is better to get 8mm better insulated leads

I'm a fan of the Aeroflow Xpro. Used them for years without an issue. I also like that they have DIY kits

I nearly bought them. Finger on the button. Thought, “No, lets wait to see what the feedback is like in this thread”

Thank you if you’ve read this and given feedback.

Get some cheapies until you can get a set of Granatelli's.

I went with Aeroflow 8.5mm. Paid $75.
Low ohm.

What are people’s thoughts on the “titanium”/fiber glass heat sleeves? $30 or so. Go over the leads down in between the manifold.

How do you find those fabric heatshields over say the metal ones?
Bought some leads recently and am looking at getting some covers.
They seem interesting
