Changed plugs, and now no power

[rbf351]

Had Denso 5346 IKH24 that i got with the JB4 kit over 10,000 miles ago. my startup has been very rough so i changed the plugs to Denso 5346 IKH24 that i got from amazon, gapped them to the same .022 and now the car has no power. tried a few 0-60 with launch control, and it takes over 6 seconds to get there. Gas is no different, been using 93 from the same place I have been getting gas since i got the car a year ago.

When I took out the plugs that have been used for the last 10,000 miles they were now gapped at .024 and we originally .022. i'm thinking about putting those back in and see if i have power again. Other than that would could be the issue?

I know these logs aren't much, but hopefully it can show something

I'm willing to bet you got fake plugs from amazon. Never buy something you need to be authentic from there, they don't have any way of properly checking authenticity of the stuff they have in their warehouses. Even if the specific vendor you bought them from at Amz was legit, Amz itself can pull from other merchant's less than reputable stock instead.

I think you are right, i put the old plugs back in and the car is running normal again. Even my 13yr old son was complaining

Hey at least you caught it before anything bad could have happened other than just being down on power.

Buy plugs from K8stingerstore, burgermotorsports, kdmwarehouse

I must have been lucky. Purchased 2 sets from Amz and didn't have any issues related to plugs....

Accessories from amazon are fine - not sure I’d want to buy crucial engine parts there.

Don’t ever buy spark plugs off Amazon. Too many fakes out there.
