The close proximity of the engines header to the alternator, is what dramatically reduces the alternators life, even with a wrapped header. Our V2 heat shield will help to extend your alternators life by keeping direct header heat away. These can be used with the OEM exhaust manifold or any aftermarket header including the tight fitting 2J Racing Medusa V1 & V2 header.


We have now modified the upper portion to allow clearance of the AC line that runs above the alternator. This modification will also allow you to run your factory Nissan engine cover if you wish.


*will only mount to the alternator using an unmodified/unshaved alternator bracket*

Fits 02-06 Sentra SER, SPEC V and Altima 2.5. Also fit 2nd gen QR25 swaps in the B15
