MACE ALLOY MAIN CAP GIRDLE TO SUIT FORD FAIRLANE NA NC NF NL AU MPFI INTECH VCT SOHC 12V 3.9L 4.0L I6This main cap girdle is designed to reduce "capwalk", stop block web flexing and eliminate cracking of the main caps block webs; this is achieved by boxing in the main caps. Our lightweight girdle evenly distributes load and dampens harmonics by bolting the main cap studs together to create a super strong rectangular cage. The brace nearly doubles the main web support area in the engine. Securing the loose end of the main studs provides stability

This main cap girdle is designed to reduce "capwalk", stop block web flexing and eliminate cracking of the main caps/block webs; this is achieved by boxing in the main caps. Our lightweight girdle evenly distributes load and dampens harmonics by bolting the main cap studs together to create a super strong rectangular cage. The brace nearly doubles the main web support area in the engine. Securing the loose end of the main studs provides stability unequaled even by a 4-bolt mains setup.

In addition, due to the close proximity of the main stud girdle to the crankshaft and rods it also aids in stripping oil off of the crank, which in itself yields a net gain in HP.

Fabricated from 10mm thick high strength aluminium, these girdles are a must for high rpm/high horsepower applications where block rigidity is critical.

Maintained airflow
Difficult to know how well it’s filtering the air. But it installed correctly and I am still getting good airflow through my vents

High-Quality Cabin Filter with Carbon Pre-Filter
This filter was easy to install in a 2010 Honda Fit. I wanted a HEPA filter given my severe allergies. The honeycomb carbon side looks similar to my Winix and Air Doctor carbon filters so it felt high quality.

Good alternative without
This filter kit is a convenient all-in-one replacement for my 2011–2017 Honda Odyssey. Both the cabin and engine air filters fit perfectly and were easy to swap out in just a few minutes. The quality feels solid, and it’s great not having to buy the filters separately. A quick upgrade that helps the van run cleaner and keeps the cabin air fresh.
