*Note: This kit only fits 460cc non-hemi 10-Bolt engines. Filter should be sprayed with K&N type oil, especially in dirt applications. Oil not included - click here. Billet aluminum flywheel REQUIRED. These kits are intended for experienced engine builders. Some clearancing, fitment, or other engine building "tricks" may be needed. Picture for reference only.
