I want to change out the spark plugs which are NGK iradium and are at 89k.
I decided on going with Denso K20HR-U11 oem copper spark plugs but noticed the pre-gap is .044.
The manufacturer recommendation for 2008 SR5 4x2 V6 is .043.
Should these .044 pre-gap plugs be adjusted to .043?
Thanks

You can regap them if you want too, but that tiny bit of difference won't make much if any difference if at all and won't do any damage, it's only 1/1000th of an inch too big.
